Study Notes

Bridge Formulas

Bridge formulas allow for less maximum axle weight for closely spaced axles.

Containerized Loads

Containerized loads are primarily for freight transported partially by rail or ship.

Alcohol Consumption and Driving

A waiting period of 4 hours after drinking alcohol is recommended before driving.

Cargo Inspection

Cargo should be re-inspected 50 miles after the initial pre-trip inspection.

Looking Ahead While Driving

Drivers should look 12-15 seconds ahead when driving.
In urban areas, the recommended distance to look ahead is 1 block.

Gross Vehicle Weight (GVW)

Gross Vehicle Weight is defined as the total weight of a vehicle and its load.

DUI Consequences

A second DUI conviction results in a lifetime loss of the commercial driver's license (CDL).
A first DUI conviction leads to a one-year revocation of driving privileges.

Railroad Crossing Safety

A typical tractor-trailer takes 14 seconds to clear a single railroad track and over 15 seconds for a double track.
Two railroad grade crossing violations within three years incur a 120-day disqualification of the CDL.

Out of Service Violations

A second violation of an out-of-service order in a 10-year span results in at least a 1-year CDL suspension.

Backing Maneuvers

During the "backing into alley dock" maneuver, the vehicle must be no more than 36 inches from the simulated dock.

Load Regulations

Flags or lights are required on loads extending 4 or more feet beyond the vehicle's rear.

Road Conditions

"Bleeding tar" refers to tar surfacing that becomes slippery in hot weather, affecting driving safety.

Skid Recovery

To recover from a drive wheel braking skid, stop braking and counter-steer.

Engine Compartment Checks

Checking the engine compartment during a seven-step inspection does not include evaluating the oil pressure gauge.

Following Distance

A vehicle measuring 30 feet should maintain a 4-second following distance when traveling at 55 mph.

BAC Regulations

A blood alcohol concentration (BAC) of 0.02 while stopped at a rest area results in a 24-hour out-of-service period.

Leaf Spring Condition

If one-fourth of any leaf spring is broken, the vehicle must be put out of service.

Front Axle Weight

Insufficient weight on the front axle can result in steering difficulties.
