New York CDL Practice Test

Correct answer: At least 18 years old

New York issues Class A, B, and C CDLs at age 18. Until you turn 21, however, you may drive a CMV only within New York State (intrastate commerce).

Correct answer: Drive interstate, transport students in a school bus, or transport hazardous materials

Under 21, you can drive a CMV only for intrastate commerce (within New York State), cannot transport students in a school bus, and cannot transport hazardous material.

Correct answer: Hold a NYS driver license that is not suspended, revoked, or cancelled

To obtain a CLP you must already have a New York State driver license in good standing — not suspended, revoked, or cancelled — and apply in person at a NYS motor vehicles office.

Correct answer: 30 days after establishing residency

A driver holding a CDL issued by another jurisdiction who moves to New York must apply for a NYS CDL within 30 days after establishing residency. To keep a HazMat endorsement, the written test and background check must be repeated.

Correct answer: Multiple-choice with one correct answer out of three choices; 80% is passing

All NY CDL test questions are multiple-choice — you choose one correct answer from three choices — and the passing score for each commercial driver knowledge test is 80%.

Correct answer: English, Spanish, Chinese, and Russian — except HazMat, which is English only

The written tests for CDL Class A, B, and C and endorsements are available in English, Spanish, Chinese, and Russian only. The HazMat endorsement test is available in English only, and interpreters are never allowed on knowledge tests.

Correct answer: All written tests (knowledge and endorsement) taken at the same time

The $10.00 application fee lets you take all written knowledge and endorsement tests taken at the same time. Each required test not taken and passed at initial application costs an additional $5.

Correct answer: No less than three full business days before the test date and time

You must cancel no less than three full business days before your scheduled road test date and time. If you cancel later, you lose the skills test fee and must pay it again before rescheduling.

Correct answer: 50 or fewer points deducted

You pass by demonstrating you can inspect and operate the vehicle safely with 50 or fewer points deducted. A crash, any single traffic violation, or a dangerous action is an automatic failure.

Correct answer: 1 day

All individuals who pass a road test are instructed to wait one day before going to the DMV to receive their permanent CDL license.

Correct answer: Apply light pressure on the brakes for a short distance, then make a test stop

Water in the brakes can make them weak, apply unevenly, or grab. After deep water, keep light pressure on the brakes for a short distance to heat and dry them, then make a test stop when safe to be sure they work well.

Correct answer: Even more slippery, so you should slow down more

Be aware that as the temperature rises to where ice begins to melt, the road becomes even more slippery. Wet ice is much more slippery than ice that is not wet — slow down more.

Correct answer: Carbon monoxide can leak into the cab, making you sleepy or even killing you

Exhaust leaks are especially dangerous in winter when the cab is closed up. Loose connections could let poisonous carbon monoxide leak into your vehicle. Carbon monoxide makes you sleepy and, in large enough amounts, can kill you.

Correct answer: Every two hours or every 100 miles

Inspect the tires every two hours or every 100 miles in very hot weather. Air pressure rises with temperature — do not let air out, or the pressure will be too low when the tires cool off.

Correct answer: Remain stopped until the tire cools off

If a tire is too hot to touch, remain stopped until it cools off. Otherwise the tire may blow out or catch fire. Do not let air out to reduce the pressure.

Correct answer: Tar that rises to the road surface in hot weather, creating very slippery spots

Tar in the road pavement frequently rises to the surface in very hot weather. Spots where tar "bleeds" to the surface are very slippery, so watch for them.

Correct answer: High speeds create more heat for the tires and engine, raising the risk of tire failure or fire

High speeds create more heat for the tires and engine. In desert conditions the heat can build to a dangerous point, increasing the chance of tire failure, fire, and engine failure.

Correct answer: Shift gears while crossing the tracks

Do not shift gears while crossing railroad tracks — you could lose momentum and stall on the tracks. Never race a train to a crossing, and do not expect to hear the train over the noise inside your vehicle.

Correct answer: Between 15 and 50 feet before the nearest rail

Vehicles required to stop at railroad crossings — such as buses carrying passengers and placarded vehicles — must stop within 50 feet but not less than 15 feet from the nearest rail, then listen and look both ways for trains.

Correct answer: Double check — a train on one track can hide a train on another — and be sure you can clear all tracks

Double tracks require a double check — a train on one track may hide a train on the other. Never let traffic trap you on the tracks; be sure you can get all the way across before you start. A tractor-trailer needs at least 14 seconds to clear a single track and more than 15 seconds for a double track.
