Diamond-shaped signs are used to warn drivers of special conditions or hazards ahead. They are typically yellow or orange in color.

It is important to stay alert on highways and be ready to react to unexpected hazards. To avoid "highway hypnosis," you should avoid looking at any one thing for more than a few seconds.

Bring your vehicle to a complete stop at a crosswalk to yield the right-of-way to any vehicle or pedestrian already in the intersection. You may carefully proceed if your lane is completely clear.

Your vehicle's headlights must be activated between sunset and sunrise. Use headlights any time you are driving under conditions that lower visibility.

Fines for moving traffic violations are doubled in work zones where workers are present, as well as in school zones during indicated hours. Always drive with caution when near children, workers, and other pedestrians.

A five-sided sign is used to alert drivers to a school zone. Some pentagonal signs specifically indicate crosswalks within school zones where children or other pedestrians may be present.

When following a motorcycle, allow a greater following distance than you would when following any other vehicle. Motorcycles are able to stop and turn more quickly than larger vehicles and a driver following a motorcyclist needs time to react to their quick movements.

When you want to leave the interstate, plan ahead and watch for exit signs. Make sure you are in the correct lane at least a mile before making the exit. Do not slow down until after you have moved into the deceleration lane.

When driving in high-speed traffic, it is extremely important to stay well behind the vehicle in front of you. As your speed increases, the distance it will take for your vehicle to stop also increases.

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.

Parking within 15 feet of a fire hydrant is prohibited. Only park where it is safe and legal to do so.

Regulatory signs regulate the movement of traffic. They are usually white with black markings and must always be obeyed by motorists.

Warning signs provide notice to road users of a situation that might not be readily apparent and are usually yellow with black markings. This sign tells drivers to be alert to crossing pedestrians.

You must never attempt to share a lane with a motorcyclist, even if it looks like there is enough room to do so. Motorcyclists need to have a full lane width to be able to maneuver safely.

If your vehicle's turn signals do not work, you should use hand signals to indicate when you intend to change direction.

Every 0.02 percent increase in blood alcohol concentration nearly doubles a driver's risk of being in a fatal crash.

This advisory speed sign indicates the maximum safe speed for a highway exit (in this example, 30 mph).

Excessive speed is one of the most common contributing factors to vehicle crashes. Excessive speed does not save time and often leads to high-risk decision-making.

Nebraska's speed law requires driving at a speed that is reasonable and safe under existing conditions, within the posted speed limit. Reduce your speed any time conditions are less than perfect.

Use your low beams when driving in fog, snow, rain, or mist. Light from high beams will reflect off of precipitation, causing a glare and making it even more difficult to see. Some vehicles are equipped with fog lights that should be used in addition to low beam headlights.

The speed at which you should drive your vehicle depends on road conditions, the weather, and the legal speed limit. You may never drive above the legal speed limit. Decrease your speed when anything makes conditions less than ideal.

When driving, watch for warning signs of fatigue. You are too tired to drive safely if you are struggling to keep your eyes open, drifting from your lane, or turning up the radio and rolling down your windows to keep yourself awake. If you notice these signs, it is a good idea to find a safe place to park so you can refresh yourself with a short nap.

Worn or bald tires can increase your stopping distance and make turning more difficult. Tires without adequate tread also increase the risk of hydroplaning.

Maintain a following distance of 100 feet from snow removal equipment or other maintenance vehicles working on roadways, except to pass. Around such equipment, flying sand and chunks of ice and snow may damage surrounding vehicles. Snow removal equipment on the roadway may result in restricted visibility due to clouds of snow forming from the moving plows.

Yellow-green signs are warning signs specific to pedestrians, bicycles, playgrounds, schools, and school buses. Be especially alert to pedestrians and children when near one of these signs.
