A speed limit sign shows the maximum legal driving speed for the stretch of highway where it is posted. Driving safely may require you to travel more slowly than the posted limit. When conditions are less than ideal, drivers should slow down.

If a vehicle approaching you is using its high beams and fails to dim them, you should glance toward the right side of the road. This will keep you from being blinded by the other vehicle’s headlights and will allow you to see well enough to stay on your course until the vehicle passes.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to an upcoming traffic signal. They should be prepared to respond to a yellow light, red light, and/or cross traffic.

Signs that are brown indicate areas of cultural and historical significance or of public recreation. They can be a helpful resource when traveling in unfamiliar locations.

Crossbuck signs tell drivers to yield to trains at a railroad crossing. Drivers should not try to outdrive a train.

Once leaves become wet, they can create slippery and dangerous driving conditions. The end of daylight saving time means reduced visibility on the roads, which can create unsafe driving conditions. Slow down on slick roads and increase your following distance when rain or mist begins to fall. Just a small amount of water can mix with oil and grease on the roadway to create slippery conditions.

Yellow lines are used to separate traffic moving in opposite directions. Solid lines indicate that drivers are not permitted to pass.

This sign indicates that workers may be on or very close to the roadway ahead, so you should take special care when traveling through the area.

In some metropolitan areas, traffic lights are horizontal instead of vertical. On these signals, the red light is on the left, the yellow light is in the middle, and the green light is on the right.

The only method that effectively reduces your BAC is to not drink alcohol for a period of time. Coffee, exercise, and cold showers cannot reduce your BAC or change the effects of alcohol. They can help you remain awake, but they cannot change your BAC or make you sober.

You must yield the right-of-way to all emergency vehicles using a siren, air horn, and/or flashing red, blue, or white lights. Where possible, you must pull over to the right edge of the road. If you are in an intersection, drive through the intersection before you pull over.

This sign warns of two-way traffic ahead.

Headrests protect vehicle occupants from whiplash. Adjusting your headrest is an important step to take before driving.

This sign indicates that the road ahead becomes a divided highway. Keep to the right of the divider or median.

When intending to back up, always check behind your vehicle before getting in. Children and small objects are difficult to see from the driver’s seat. While backing, turn your head so you can see through the rear window. Do not depend only on your mirrors or sensors.

Locations where it is unlawful and unsafe to pass another vehicle include hills, curves, intersections, and railroad crossings.

Do not stop at an accident scene unless you are involved or emergency help has not yet arrived. Keep your attention on your driving and keep moving, watching for people who might be on or near the road. Never drive to the scene of an accident, fire, or other disaster just to look.

Defensive drivers judge their surroundings. In poor weather conditions, they slow down so they are able to control their vehicle. Good defensive drivers do not make risky maneuvers, such as trying to beat a red light or outdrive a train.

If you are turning left from a two-way street onto a one-way street, you should complete the turn into the lane closest to the lane you have just left.

Use your emergency signals or horn when appropriate.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to an upcoming curve in the road.

Being awake for 24 hours in a row has the same effect on your driving as a blood alcohol level of 0.10 percent.
