Hawaii CDL DMV Endorsement Passenger 2

However you choose to deal with a brake failure on a downhill slope, it is important that you make your decision as quickly as possible. The longer you wait to act, the faster your vehicle will be moving, and the harder it will become to stop.

When turning, drivers usually look in the direction of their turn. If a driver fails to signal before a turn or lane change, their body movements may still provide a clue that they are planning to turn.

At bus stops, drivers should warn passengers about potential hazards. This may include warning them to watch their step when exiting the bus by way of lowered stairways.

Most alcohol is removed from the body by the liver, which processes alcohol at a fixed rate. Despite popular belief, techniques like drinking black coffee or taking a cold shower will not accelerate this process. The only thing you can do to become sober after drinking is allow your body the time it needs to eliminate the alcohol from your system.

When asked to make a lane change during the on-road driving test, you should make the proper traffic checks, use your turn signal, and smoothly change lanes when it is safe to do so.

During the on-road driving test, do not stop, change gears, pass another vehicle, or change lanes while any part of your vehicle is in a railroad crossing.

Because they are exposed to less sunlight and warm up more slowly, shaded areas will remain icy and slippery after ice on other areas of the road has melted.

The doors of a trailer should be not be opened in the event of a cargo fire, especially if the cargo includes hazardous materials. Opening trailer doors would increase the fire's oxygen supply, potentially causing the fire to increase in size.

For safe operation, a commercial motor vehicle needs a tread depth of 4/32 of an inch in every major groove on the front tires, and a tread depth of 2/32 of an inch on other tires.

You should be cautious when passing parked vehicles. A person may step out of a parked vehicle or out from between parked vehicles without looking for oncoming traffic. A driver may begin moving their vehicle before realizing you are there.

Radial and bias-ply tires should not be used together. All wheels on a vehicle should be the same style and equally-sized.

Hydroplaning occurs on surfaces where water has collected. If there is enough water, vehicles can hydroplane at speeds as low as 30 mph. Hydroplaning becomes more likely if tires are under-inflated or if the tread is worn.

To avoid a loss of control, you should accelerate slowly when driving in poor-traction conditions, such as rain or snow.

Distractions that can affect safe driving can be classified as physical (such as reaching for an object), mental (such as talking with passenger), or both (such as talking on a hand-held phone).

Always decrease your speed when traveling through a construction area. Slow down even further if there are workers on or near the roadway.

You should accelerate very gradually when driving under conditions that create poor traction.

If you think the road surface may be becoming icy but you are not certain, you can open your window and feel the front of the side mirror, mirror support, or antenna. If ice has formed on any of these items, the road is likely becoming icy as well.

Most cases of hydraulic brake failure come from one of two causes. The brakes may fail due to a loss of hydraulic pressure or due to overuse on long hills, causing the brakes to fade.

A vehicle inspection report keeps the carrier informed about any problems that need to be fixed.

Drivers who are engaged in conversation with passengers may be distracted from the task of driving. Use extra caution when driving near distracted drivers.
