Transportation enforcement
The Class D course for expressly commissioned SADOT enforcement officers: commission limits and hand-offs, commercial vehicle, CDL, size and weight and hazmat law (SATC ch. 644, 621, 522; SAHSC ch. 505; SAAC §30.01), Burger inspections, work zones and infrastructure, incident and crash scenes, detention law and reports.
Required for Class D recruits of Transportation agencies only
The exam draws 30 questions from a bank of 60. You have 45 minutes, and you need 80% to pass. Questions apply the law to situations. To prepare, read this guide alongside the cited sections of the San Andreas codes, the 2026 Law Enforcement Reform Package and the federal authorities below. The U.S. Constitution binds every San Andreas officer. Supreme Court decisions are binding; federal circuit decisions are accepted authority, and where circuits differ the academy teaches the rule that protects rights more.
A San Andreas Department of Transportation (SADOT) enforcement officer holds Class D authority: a Special Enforcement Officer has only the powers needed for expressly designated statutory responsibilities (Act I §1.09). A transportation agency's enforcement powers exist only for expressly commissioned positions. No one exercises peace officer authority without both a lawful appointment and the qualifications the law requires, and certification alone confers no power (§1.11), so a SADOT road crew chief, engineer or flagger without an enforcement commission stops no one and writes no citations, whatever the uniform or vehicle. Be honest about the sources: no SADOT enabling statute appears in the San Andreas codes this academy teaches from. Your actual powers come from your commission and the agency's own enabling law, and you must learn them there. For teaching purposes only, this module assumes a commission covering, on state highways, commercial motor vehicle (CMV) and carrier safety, credentials and out-of-service orders (SATC chapters 644, 621 and 522, SATC §548.12 and SAAC §30.01), hazardous materials in transport, and offenses against highway work zones, traffic-control devices and highway infrastructure. That assumption is not a statement of San Andreas law. Departmental policy or an agreement cannot enlarge statutory powers (§1.12), and materially exceeding a commission is prohibited (§1.14).
The State Police course assumes a Class B agency whose mission is highway traffic safety and commercial vehicle enforcement. Under that assumption a trooper may stop an ordinary passenger car for speeding on a freeway; under this module's assumption a SADOT officer may not, because general moving-violation enforcement is not in the listed subject matter. Statewide subject-matter jurisdiction is not general statewide criminal authority (§1.09). A SADOT officer runs no routine patrol, makes no stops unrelated to the commission, does no drug interdiction, and does not leave the state highway to enforce on city streets or county roads. Crimes against persons that happen to occur in a work zone, such as an assault on a flagger, are not work-zone offenses. When the officer sees a crime outside the commission, the rule is to report it, keep people safe, document what was seen and hand it to the agency with jurisdiction. The one exception is an immediate threat of death or serious bodily injury: the emergency route in Act VII §7.03 and §7.05 allows only the action the emergency requires, to the extent the law allows, with prompt notice to the agency with jurisdiction and no continuing jurisdiction afterwards. A Class D commission is not a lower rank either; no class is superior in rank or command to another (§1.04).
State highways run through every county and many cities, and concurrency is normal: the State Police, the county sheriff and the city police keep their authority on a highway even while a SADOT officer works it (§1.13). Command at an incident follows primary responsibility, law and agreement, not class, size or arrival order, and each agency keeps responsibility for supervising and disciplining its own people (§7.07). Route 68 is the Los Santos/Blaine county line: outside city limits, a matter north of it belongs to the Blaine County Sheriff's Office (BCSO) and one south of it to the Los Santos County Sheriff's Office (LSCSO); inside a city, the city police department has primary responsibility while the county keeps concurrent authority. SADOT is not a 911 agency. Class D officers join mutual aid only as their enabling statutes allow, and an agreement never turns a limited-authority officer into a general-authority one (§7.09); agreements set procedures but confer no powers (§7.06). A joint investigation must identify the lead agency, evidence custody, information sharing and arrest authority, and gives no participant a power it did not already hold (§7.08). Extraterritorial actions are reported to the employing agency and the agency with primary jurisdiction (§7.11), and withdrawal from a joint operation is coordinated so no one is left in unreasonable danger (§7.13).
Most of SATC chapter 644 is civil. A Regulation is enforced by administrative penalty and creates no criminal record without a separate criminal charge (SAPC §1.09); the entries assign "Civil citation; no custodial arrest". The civil provisions are the USDOT number (§644.02), the medical examiner's certificate (§644.03), an accurate record of duty status and hours-of-service rules (§644.04), FMCSA operating authority (§644.05), cargo securement (§644.06), hazmat placards (§644.07) and driving beyond the federal hours limits, including the 11-hour driving and 14-hour on-duty limits (§644.09). Failing to conduct and document a pre-trip inspection (SABCC §171.65), failing to stop at a required weigh station (SABCC §171.66) and non-compliant or inoperative CMV lighting (SATC §547R.09, §547R.10) are civil too. Two are not civil: handheld phone use by a CMV operator is a Traffic Infraction (§644.01), and a commercial driver who knowingly makes false entries in an electronic logging device (ELD) or paper log commits Driver Logbook Falsification (§644.08), a Class A Misdemeanor with discretionary custodial arrest. Careless gaps and errors are §644.04; the word that makes §644.08 a crime is knowingly. Loads have three levels: loose or spilling cargo on any vehicle is the infraction §547.02, improper CMV securement is the civil §644.06, and intentionally or recklessly letting a load fall onto a highway and create a hazard is Creating a Public Road Hazard (SAPC §38.71), a Class B Misdemeanor.
SATC §644.10 sets the inspection levels: Level I is a full driver and vehicle inspection, Level II a walk-around, Level III a driver and credential inspection only, Level IV a special one-time inspection, Level V a vehicle-only inspection with the driver absent, and Level VI an inspection for radioactive or hazardous material. An out-of-service condition found at any level bars operation until corrected. An authorized inspector may issue an out-of-service order for a CMV or driver whose condition makes continued operation unsafe: a critical defect, an hours-of-service violation, falsified logs or an imminent hazard (SAAC §30.01); this module assumes the SADOT commission makes its officers authorized inspectors. For civil hours and defect violations the order, not an arrest, is the tool. Operating a vehicle declared out of service, or directing another person to operate it, before the conditions of the order have been satisfied is SATC §548.12, a Class B Misdemeanor with discretionary custodial arrest and mandatory impound; its entry also lists a CDL disqualification consequence, and SAAC §10.01 makes impound mandatory for operation while declared out of service. Because the offense turns on the order's conditions, write them down exactly: the defect or violation, what must be done to satisfy the order, the time it was served and on whom. A driver who satisfies the stated conditions and then drives commits no §548.12 offense.
Commercial licensing has its own chapter, and the arrest authority differs by section. Operating a CMV that requires a CDL without a valid CDL of the appropriate class and endorsement is §522.01, a Class A Misdemeanor with discretionary arrest and discretionary impound. Knowingly making a false statement, submitting a forged document or omitting required information on a CDL application or a federally required medical examiner's certificate is §522.02, a State Jail Felony with mandatory custodial arrest and permanent CDL disqualification on conviction; merely lacking a valid medical certificate is the civil §644.03. Operating a CMV while the CDL is suspended, revoked or disqualified is §522.03, a Class A Misdemeanor with mandatory custodial arrest and mandatory impound. Operating a CMV of a class, or carrying a cargo type such as hazardous materials or passengers, without the required endorsement is §522.04, a Class B Misdemeanor. A CDL holder operating a CMV at or above the lower commercial alcohol threshold commits §522.05, with mandatory custodial arrest and mandatory impound; the commercial DWI offense in SATC §49V.09 uses 0.04. Testing follows the Constitution: a breath test, but not a blood test, may be required as a search incident to a drunk-driving arrest (Birchfield v. North Dakota), and the natural dissipation of alcohol does not by itself excuse a warrant for blood (Missouri v. McNeely).
Size and weight are SATC chapter 621. Without a valid permit, a vehicle or combination may not exceed a width of 8 feet 6 inches (102 inches), a height of 14 feet, a gross weight of 80,000 pounds, a single-axle weight of 20,000 pounds, a tandem-axle weight of 34,000 pounds or a semitrailer length of 59 feet; exceeding any one of them is §621.05, a Class B Misdemeanor with mandatory impound (§621.07 is the reference table). Each limit stands alone, so a truck under the gross limit can still be over on an axle group. A valid permit is the whole difference: a permitted oversize load within its permit commits no §621.05 offense. The code also has civil provisions for permitless oversize or overweight loads (§621.04) and for overweight commercial vehicles on a road classification (§621.03); the officer documents the facts and the charging choice follows them. Ignoring a permit's escort, signage, flag, light, route or curfew terms is §621.06 (Class B). Exceeding the posted limit of a bridge, overpass or road segment is §621.02 (Class B, mandatory impound). Bridge limits are posted in tons, and a ton is 2,000 pounds, so a 15-ton posting means 30,000 pounds. Record the posted limit, the weight and its source (scale ticket or documents), the load, and how each dimension was measured.
Hazardous materials in transport add criminal offenses and a safety discipline. A commercial driver who transports placard-quantity hazardous materials without a Hazardous Materials Endorsement on the CDL commits SAHSC §505.02, a Class A Misdemeanor; the elements are placard-quantity hazmat, a commercial driver and no endorsement. The same facts can also meet the CDL endorsement offense (SATC §522.04). Missing placards are the civil SATC §644.07. A person who causes or is responsible for a release at or above the reportable quantity and fails to immediately notify both the National Response Center and state authorities commits SAHSC §505.05 (Class A); a 911 call for fire response is not that notice. A faded but substantially legible label is the minor §505.08. Transporting explosives without a valid transportation permit, without the required DOT placards, outside designated transport routes or in an uncertified vehicle is SAPC §46.62, a Class A Misdemeanor. At a hazmat incident, general practice is to approach and stage upwind and uphill, read placards from a distance, isolate the area, deny entry and let the fire service lead. Refusing a lawful order from a fire officer or incident commander at a hazmat incident is SAPC §28.32, and entering or interfering with an emergency operational area after being told to stay clear is SATC §546.03; both are Class A Misdemeanors.
The academy treats commercial motor carriage as a closely regulated industry, as the State Police course does, so warrantless regulatory inspections are measured by New York v. Burger. They are reasonable when a substantial government interest informs the regulatory scheme, warrantless inspections are necessary to further it, and the inspection program, in the certainty and regularity of its application, substitutes for a warrant by advising carriers that inspections will occur and by limiting the inspector's discretion in time, place and scope. Inspectors who pick trucks and search areas at whim fail the third condition. Evidence found within a valid inspection's scope is admissible even though the scheme and the penal law share goals. The sources are thin: §644.10 and SAAC §30.01 describe inspection levels and out-of-service orders, but no statute in these codes sets out a full inspection scheme, so stay inside the recognised inspection. Homes are different: administrative entries into dwellings need a warrant (Camara v. Municipal Court), so a one-truck carrier's records kept in his kitchen need consent or a warrant. A program whose primary purpose is general crime control, such as finding drug couriers, is unlawful whatever its label (City of Indianapolis v. Edmond).
An inspection is limited to what the scheme authorizes. A Level III credential inspection examines the driver's licence, medical certificate and records of duty status; it is not authority to search personal bags, the sleeper berth or a phone. Searching a cell phone's contents generally needs a warrant (Riley v. California). Going beyond the inspection needs its own justification: consent, probable cause under an established exception such as the automobile exception (Carroll v. United States), or a warrant. Consent must be voluntary (Schneckloth v. Bustamonte), and its scope is what a reasonable person would understand from the exchange (Florida v. Jimeno): a driver who hands over his ELD tablet and says "you can look at my logs on this" has not consented to a search of his duffel bag. Contraband in plain view from a lawful vantage point may be seized when its incriminating character is immediately apparent (Horton v. California), but moving things to see more is a search (Arizona v. Hicks). When the purpose shifts to gathering evidence of a particular crime beyond the scheme, the academy rule is to stop and obtain a criminal warrant on probable cause unless an established exception plainly applies; if the crime is outside the SADOT commission, the agency with jurisdiction makes that decision and does that work.
The Fourth Amendment governs SADOT stops as it does any other. A stop within the commission needs probable cause of a violation in the subject matter, or reasonable suspicion for a brief investigative detention (Terry v. Ohio). Probable cause makes a stop valid whatever the officer's motive (Whren v. United States), but Whren does not enlarge a Class D commission, so a hunch about stolen cargo or drugs is referred. Random, suspicionless stops of passenger cars to check licences and registration are unreasonable (Delaware v. Prouse). Authority ends when the stop's tasks are, or reasonably should have been, completed, and the officer may not prolong it for a dog sniff without independent reasonable suspicion (Rodriguez v. United States), though a sniff that does not prolong it is not a search (Illinois v. Caballes). A long inspection diligently pursued within its scope is lawful (United States v. Sharpe); no source sets a minute limit. Drivers and passengers may be ordered out (Pennsylvania v. Mimms, Maryland v. Wilson); a passenger is seized too (Brendlin v. California) and may be frisked on reasonable suspicion of being armed and dangerous (Arizona v. Johnson). Refusing to give name, date of birth and address after a lawful stop is SAPC §38.08 (Hiibel v. Sixth Judicial District Court). Ordinary roadside questioning is not custody, but an arrested, handcuffed driver gets Miranda warnings before interrogation (Berkemer v. McCarty).
Operating a vehicle in violation of a posted sign, flagger instruction or reduced speed limit in an active construction or maintenance work zone is SATC §544.04 (Class C Misdemeanor). Exceeding the posted reduced limit in a work zone while workers are actively present is the separate, double-fine infraction §545.44; with no workers present that section does not apply. Disobeying a certified construction-zone flagger or a uniformed officer lawfully directing traffic is also the infraction §545.40, so one act can meet both §545.40 and §544.04. Failing to vacate the nearest lane when possible, or to slow, for a stationary emergency vehicle, tow truck or highway-maintenance vehicle with activated warning lights is §545.49, a Class C Misdemeanor that becomes Class B if it causes bodily injury. DWI in a construction or maintenance zone where workers are present is §49V.12. Placing an unauthorized sign or device that purports to regulate, warn or guide traffic is §544.02 (Class B); removing, defacing or stealing a lawful sign is §544.05 (Class A); knowingly disabling a traffic signal and creating a hazard is §544.03, a State Jail Felony with mandatory arrest; and intentionally damaging or impairing public infrastructure, including traffic control systems, so as to interrupt service or create a hazard is SAPC §38.86, a 2nd Degree Felony.
Traffic-incident management is general professional practice, not statute. On arrival, protect the scene from approaching traffic first, using the patrol vehicle and warning lights to shield the work area, then reach and aid the injured as soon as it is safe, because a second crash into a stopped scene is a serious danger to responders. Ask early about fuel, cargo and placards. Once the injured are cared for and the evidence is documented, open the travel lanes as soon as practicable to reduce secondary crashes. A driver who can safely move a vehicle after a minor crash must move it off the travel lanes (§550.11), and an officer may impound a vehicle that is abandoned, blocking traffic or a hazard (SAAC §10.02). People may watch and record from a lawful place, since recording officers in public is protected (Glik v. Cunniffe), but entering the operational area after being told to stay clear is §546.03. Drivers involved in crashes have their own duties: leaving a crash that injured someone without stopping and rendering reasonable assistance is §550.03 (3rd Degree Felony) and becomes §550.04 for serious bodily injury; a driver who stays but fails to render aid, including calling for medical help, commits §550.06; and failing to report a qualifying crash no officer investigated is §550.10.
At a CMV crash, the agency with primary responsibility for the incident leads the crash and any criminal investigation (§7.07); a fatal or hit-and-run case belongs to it. The SADOT officer's contribution is the commercial side: inspect the vehicle and driver's credentials and records of duty status, place the vehicle or driver out of service where SAAC §30.01 applies, check the load and placards, and share findings with the lead agency. A report is evidence. It states the commission and the subject-matter basis, the location on the state highway, the facts that justified the stop or inspection, the inspection level, each measurement and how it was taken, and the out-of-service order's conditions. It keeps civil Regulations separate from criminal charges in JusticeLink, records every referral and notice (§7.11), and links body-camera video and CAD entries. For §644.08 it must show the facts proving the entries were knowingly false, such as fuel receipts or weigh-station times that contradict the log. Favorable evidence, including impeachment such as an out-of-date scale calibration, goes to the prosecutor (Brady v. Maryland, Kyles v. Whitley). Preserve everything: failing to preserve potentially useful evidence violates due process only in bad faith (Arizona v. Youngblood), but the defense will ask. A knowingly false report or fabricated probable cause is a felony (SAPC §38.81).
