Strategies to avoid becoming an aggressive driver include having realistic expectations about your travel time and the possibility of delays; driving an appropriate speed and keeping a reasonable following distance; avoiding gesturing at other drivers; and keeping your hands on the wheel.

2. When transporting a load, you should inspect the cargo:

Only before starting to drive.

At the end of each day.

Every time you take a break.

Cargo and its securement must be inspected every time you take a break during a trip. Be sure to inspect the cargo at least every 150 miles.

3. If approaching a railroad crossing while driving a placarded vehicle, you should always:

Activate your four-way flashers.

Stop within five feet of the tracks.

Change gears while on the tracks.

Change lanes while on the tracks.

If approaching a railroad crossing while driving a transit bus, school bus, or placarded vehicle, special procedures apply. Before crossing, stop your vehicle within 50 feet of, but not less than 15 feet from, the nearest rail. Activate your four-way flashers while crossing. Do not stop, change gears, or change lanes while any part of your vehicle is proceeding across the tracks.

4. If the spring brakes are activated, you should never:

Push down the brake pedal.

Open the hood.

Release air from the air storage tanks.

Is a good way to maximize time.

Is encouraged on long trips.

To reduce the chances of driving distracted, you should avoid eating, drinking, or smoking while driving. Anything that diverts attention from the task of driving is a distraction.

Not worry because the tracks are likely abandoned.

Park your vehicle and walk up to the tracks to determine if a train is approaching.

Look down the tracks in both directions to ensure that no trains are approaching.

Do whatever surrounding vehicles are doing.

A passive railroad crossing is a crossing that lacks control devices, like gates or warning lights. Before crossing a passive railroad crossing, you should search the tracks for approaching trains coming from either direction.

7. Off-ramps:

Are usually safest for trucks.

Can be dangerous for trucks.

Should not be used by trucks.
