B.Up to 4 inches before steering linkages engage
C.No more than 0.5 inches under any mechanical condition
D.Approximately 3 inches of free play at engine idle
Explanation: According to the vehicle inspection standards in the Oregon Commercial Driver Manual, steering wheel play should not exceed approximately 10 degrees, which is about 2 inches of movement at the rim of a 20-inch steering wheel.
3What emergency safety equipment is legally required to be on board every commercial passenger bus operating in Oregon?
A.Spare electrical fuses (unless circuit breakers are used), three reflective red warning triangles, and a properly rated, charged fire extinguisher

C.An automated external defibrillator (AED), a two-way emergency radio, and tire chains
D.A spare tire, six road flares, and emergency blanket packs for all seated passengers
Explanation: Federal regulations and the Oregon CDL manual require every commercial bus to carry spare electrical fuses (unless equipped with circuit breakers), three reflective warning triangles, and a properly rated and charged fire extinguisher.
4Before departing on a passenger bus trip, what must the driver verify regarding the bus interior emergency exit windows and roof hatches?
A.They must be tested, operate smoothly, latch securely, and have functional interior warning buzzers or indicator lights when opened
B.They must be securely padlocked from the inside to prevent unauthorized passenger tampering while in motion
C.They must be opened at least two inches during pre-trip to ensure continuous cabin ventilation
D.They only require visual inspection once per month by certified maintenance technicians
Explanation: During pre-trip inspection, the driver must check that all emergency exit windows and roof hatches open freely, latch properly, and activate audible or visual warning devices when unlatched with the electrical system energized.
5What is the primary function of the standee line painted on the floor of a commercial transit bus?
A.To mark the forward boundary beyond which no passenger may stand while the vehicle is in motion
B.To indicate the designated priority seating zone for elderly passengers
C.To establish the required separation distance between boarding passengers and fareboxes
D.To show maintenance crews where the front axle weight threshold begins
Explanation: Under 49 CFR 392.62 and Oregon CDL rules, no bus transporting passengers may be operated with passengers standing forward of the white or marked line (the standee line) painted on the floor behind the driver's seat.
6How must baggage, packages, and freight be stowed in a passenger bus to satisfy safety regulations?
A.Stowed in a manner that keeps all aisles, stairwells, and emergency exits completely clear, secured against sliding or falling
B.Stacked in empty rear passenger seats provided total seat weight does not exceed 150 pounds per bench
C.Placed along the center aisle as long as passengers can step over individual bags without tripping
D.Positioned directly behind the driver's seat up to window height to serve as a safety partition
Explanation: The Oregon CDL manual mandates that baggage and cargo must be stowed so that all aisles and emergency exits remain completely unobstructed, and items must be secured so they cannot shift or fall and injure passengers.
7According to Section 4 of the Oregon Commercial Driver Manual, which hazardous material must never be transported on a commercial passenger bus?
A.Division 2.3 poison gas
B.Small-arms ammunition
C.Emergency hospital supplies
D.Drugs carried as authorized cargo
Explanation: Section 4 says a bus must never carry Division 2.3 poison gas. It also lists other forbidden materials and limits the amount of otherwise permitted hazardous materials.
8What is the maximum total weight of permitted hazardous materials that may be carried on a commercial passenger-carrying bus?
A.No more than 500 pounds total, with no more than 100 pounds of any single class of permitted hazardous material
B.No more than 1,000 pounds total regardless of the number of classes
C.Up to 2,000 pounds if secured in a separate locked luggage compartment
D.No hazardous materials of any kind or quantity may ever be carried on a bus
Explanation: Buses may carry small quantities of certain allowable hazardous materials, but the total gross weight must never exceed 500 pounds, and no more than 100 pounds of any single permitted class may be transported.
9Under ORS 811.460, what must a commercial passenger bus driver do at a railroad-highway grade crossing that is not exempt?
A.Stop at a clearly marked stop line or, if none exists, between 15 and 50 feet from the nearest rail, then look and listen before crossing
B.Slow down to 10 mph and cross without stopping if no warning lights are flashing
C.Stop exactly 5 feet from the nearest rail, honk the horn twice, and proceed across in second gear
D.Stop only if a train is actively sounding its whistle or if crossing gates are fully lowered
Explanation: ORS 811.460 requires a qualifying bus to stop at the marked stop line or, if there is none, not less than 15 feet and not more than 50 feet from the nearest rail. The Oregon CDL manual separately instructs bus drivers to open the forward door and driver window so they can see and hear better.
10Why is shifting manual transmission gears prohibited while a commercial passenger bus is crossing railroad tracks?
A.Shifting gears increases the risk of stalling the bus or missing a gear while directly on the tracks
B.Gear changes damage the automatic transmission fluid pump on crossing vibrations
C.Rail crossing track surfaces cause premature clutch friction plate wear
D.Oregon statutes require crossing tracks at maximum engine governed RPM in neutral
Explanation: Drivers must never shift gears while crossing railroad tracks because missing a gear or stalling the engine leaves the passenger bus stranded in the path of oncoming trains.
