When driving on packed snow, you should cut your usual speed in half. Use snow tires or chains when the roads are covered in snow.

A white rectangular sign indicates that you must obey the stated rule. This sign means that drivers should not pass other vehicles for any reason.

Rather than stopping (as you would when entering other roads), you must use the merging or acceleration lane to speed up and smoothly merge with fast-moving traffic already on the interstate.

Slow down and proceed with caution if you see animals that are standing near the roadway. They may unexpectedly bolt or change direction at the last moment. Some animals travel in packs, so there may be more animals just out of sight that are also near the road.

When driving a vehicle equipped with an Anti-Lock Braking System (ABS), a driver should press the brake pedal firmly when stopping on a snowy or icy surface. The ABS will pump the brakes more rapidly than a driver would be able to.

Blind or partially blind pedestrians may carry a white cane or use the assistance of a guide dog. You must yield the right-of-way to a pedestrian with a guide dog or a white cane.

This sign warns of a winding road ahead.

Your vehicle's blind spots are the areas that you cannot see in your mirrors. Look over the appropriate shoulder to check your blind spot when changing lanes.

You should always slow down before entering a curve. You may not be able to see hazards ahead and braking in a curve may cause your vehicle to skid.

Warning signs alert drivers to upcoming hazards and are usually yellow with black markings. This sign warns drivers about potential traffic merging into their lane from the right.

If you refuse to take a test to determine your blood alcohol content (BAC), your operator’s license will be suspended for at least 45 days. You will be required to install and maintain an ignition interlock device (IID) as a condition of reinstatement.

If multiple vehicles arrive at the same time to an intersection that is not controlled by signs or signals, the driver on the right has the right-of-way. Drivers should then proceed in the order that they arrive to the intersection.

It is necessary to follow farther behind a large truck than you would if following a passenger vehicle because trucks have larger blind spots.

At a stop sign, you must come to a full stop and check for traffic in all directions before proceeding.

You may never drive off the paved or main-traveled portion of the road and onto the shoulder to pass another vehicle.

Drivers who are 16 or 17 years of age are not permitted to use any type of cell phone or mobile electronic device while driving, including hands-free devices. The DMV will suspend the driver license of a 16- or 17-year-old for any conviction of using a cell phone or text messaging device while driving.

This sign warns that there is a flag person ahead. Always follow directions given by a flagger. Flaggers normally wear orange or yellow vests, yellow-green shirts, or bright jackets. They use paddles and red flags to direct traffic through the work zone and to let workers or construction vehicles cross the road.

Drivers of passenger vehicles share the road with many other users, including motorcycle, moped, and scooter riders. Watch for these slow-moving vehicles ahead of you so you have time to change lanes or slow down safely. Slowing too suddenly can cause a crash.

When driving in a work zone, keep a safe distance between your vehicle and traffic barriers, trucks, construction equipment, workers, and other vehicles. Increase your following distance and do not tailgate.

On rainy, snowy, or foggy days, it may be difficult for other drivers to see your vehicle. Under these conditions, headlights make your vehicle easier to see. If the weather requires you to turn on your windshield wipers, you must also turn on your low beam headlights.

Drivers turning left must yield to oncoming vehicles that are driving straight ahead. A turning driver may only proceed when they can safely turn without affecting oncoming traffic.

This sign indicates that the road may be slippery when wet. Exercise caution when driving on a slippery road.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign tells drivers to slow down and prepare for an abrupt change in direction at an extreme angle.

When changing lanes, look over your shoulder in the direction you plan to move. Check for obstructions near the rear corners of your vehicle. These areas are called “blind spots” because you cannot see them by using your mirrors.

If you begin to skid on a wet or icy road, take your foot off the accelerator, stay off the brakes, and turn your steering wheel in the direction of the skid. However, if you have anti-lock brakes, you should apply your brakes firmly and steer straight ahead.
