If the road appears to be wet but the wheels of other vehicles are no longer generating spray, ice has formed on the road. Drive with extra caution when operating on wet or icy roads.

Black ice is a thin layer of ice that is clear enough for the road surface to be seen through it. A road covered in black ice may look like it is merely wet instead of icy. Always be on the lookout for black ice if a road surface looks wet and temperatures are around the freezing mark.

If you find yourself being tailgated by another driver, you should increase your following distance and avoid making quick moves. Increasing your speed may only result in the other driver continuing to tailgate you at a higher speed. Do not turn on your taillights or flash your brake lights at the other driver.

Backing a CMV is always dangerous due to limited visibility, so using a helper to monitor your blind spots is encouraged whenever possible.

Maneuvers that may be included in the basic vehicle control skills test include straight line backing, offset back/right parking, offset back/left parking, driver side parallel parking, conventional parallel parking, and alley docking.

If you must stop on the side of the road, it is important to turn on your four-way emergency flashers to warn other road users.

Backing is always dangerous because you cannot see everything behind your vehicle. Especially if you are unfamiliar with the area, you should get out of your vehicle and familiarize yourself with your path of travel before beginning to back up.

All commercial motor vehicles are required to be equipped with the proper emergency equipment. This may include spare electrical fuses; three red reflective triangles, six fuses, or three liquid burning flares; and at least one properly charged and rated fire extinguisher.

If your hydraulic braking system will not build up the pressure needed to slow or stop your vehicle, there are a few possible solutions. Try shifting into a lower gear, pumping the brakes, and/or using the emergency brake.

Distractions while driving can be physical (such as reaching for an object), mental (such as making conversation with a passenger), or both (such as holding a phone to send texts).

Driving while distracted may result in slowed perception, delayed decision-making, and improper actions. Watch for distracted drivers and avoid them, when possible.

Backing up is always dangerous because it is impossible to see everything behind your vehicle. If you must drive in reverse, use a helper, if possible.

Driving in fog is always dangerous and should be avoided entirely if at all possible. If you must drive in fog, be sure to turn on your low beam headlights and fog lights, even during the daytime.

People sometimes damage unattended buses. Before driving a bus that has been unattended, you should check the interior to confirm that everything is in proper condition.

Make a point of checking your mirrors often when making tight maneuvers.

To reduce the risk of distraction, bus drivers should not engage in conversation with passengers. Avoid fueling a bus while passengers are on board. Do not tow or push a disabled bus with riders aboard the vehicle, unless it would be unsafe for the passengers to exit the bus at the location where it has stalled.

If an emergency vehicle using its flashing lights is stopped on the side of a multilane road, move over laws require drivers to vacate the lane directly next to the vehicle, if possible. If a driver cannot move over safely, they must slow down and proceed with caution.

Check your tires regularly when looking in your mirrors. This helps ensure that you will notice a tire fire, if one should happen. Tire fires may occur when a tire is under-inflated, if dual tires are touching, or if the tires are otherwise overheated.

Rust around wheel nuts may mean that they are loose. Check the tightness of the nuts if you see any rust in the area.

Stopping distance is affected by a vehicle's speed. The faster you are driving, the longer your stopping distance will become.
