After a vehicle's engine is started, the engine's oil pressure should rise to its normal level within seconds. Do not drive a vehicle with oil pressure that is too low.

You should never rely only on warning signals to alert you to an approaching train. Never try to race a train to a crossing. If there are multiple tracks at a crossing, be sure to check all tracks in both directions before starting to cross.

If a vehicle is coming toward you while using its high beam headlights, glance away from the headlights and toward the right side of the road until the vehicle has passed. This will keep you from being blinded by the lights.

The adjustment of your mirrors should be checked prior to the start of all trips. Adjust your mirrors as needed.

Operators driving too fast is a major cause of fatal crashes. You must continually adjust your speed to a rate that is safe for road and traffic conditions.

Alcohol impairment begins long before the legal limit is reached. A 200-pound person will reach a blood alcohol concentration (BAC) of 0.02 percent after a single drink.

When examining the air and electrical lines as part of your vehicle inspection test, you must listen for leaks. Ensure that the air hoses and electrical lines are not cut, chafed, spliced, or worn. Make sure air and electrical lines are not tangled, pinched, or dragging against tractor parts.

If you are being tailgated, it is best to allow more room to open up in front of your vehicle. This will help you avoid the need for sudden stops, which could result in the tailgater rear-ending you, and will make it easier for the tailgater to pass. Speeding up may only make things more dangerous by prompting the other driver to continue tailgating you at a higher speed.

A rollover happens as a result of a driver changing lanes or turning too quickly.

When accelerating, speed up smoothly and gradually so your vehicle does not jerk. Rough acceleration can cause mechanical damage.

To avoid becoming an aggressive driver, begin a trip with realistic expectations of how long the trip will take, allowing extra time for traffic delays. Do not tailgate other vehicles. To avoid upsetting other drivers, do not drive slowly in the left lane and do not gesture at the drivers (even in seemingly minor ways, like shaking your head).

Cargo should be inspected before beginning a trip, within the first 50 miles of the trip, and every three hours or 150 miles traveled. The driver of a truck transporting cargo is responsible for the cargo being safely secured throughout the trip.

If you must come to a stop before making a turn during the driving skills test, you should come to a smooth stop behind any stop line, crosswalk, or stop sign. Keep your front wheels aimed straight ahead and do not let your vehicle roll. If stopping behind another vehicle, stop where you are still able to see the rear tires of the vehicle ahead of you.

It is important to communicate your intentions to others on the road. Make sure to signal before turning or changing lanes, even if no other vehicles are nearby.

Tires need to have at least 4/32 of an inch of tread depth in every major groove on the front tires, and at least 2/32 of an inch of tread depth on other tires.

The emergency exit signs on a bus must always be clearly visible. The emergency door light must work properly, if applicable.

Before a trip, ensure that the steering box is securely mounted. Check for missing nuts, bolts, and cotter keys. Be sure that there are no power steering fluid leaks and that there is no damage to power steering hoses.

When inspecting your vehicle's engine, check the belts for tightness and excessive wear. The amount of "give" that is safe for each belt in a given engine will vary, so learn what is appropriate for your vehicle.

Mandatory emergency equipment includes: at least one fire extinguisher; spare electrical fuses (unless the vehicle is equipped with circuit breakers); and warning devices for parked vehicles (such as reflective triangles).

If a pre-trip inspection reveals a load to be oversize, the driver must confirm that all required signs, flags, lamps, and reflectors are safely and properly mounted, and that and all required permits are in their possession.
