Maryland CDL Permit Test - Knowledge Test Class A

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.

Never apply the brake pedal if your spring breaks are activated. Brakes can be damaged if they are subject to both springs and air pressure.

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.

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.

On- and off-ramps can be dangerous when driving a truck. Remember that posted speed limits for ramps may be safe for cars but too fast for trucks.

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.

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.
