This is a "Keep right" sign. It indicates that a traffic island, median, or barrier is ahead and that drivers must keep to the right of it.

At a yield sign, you must slow down or stop, if necessary, and give the right-of-way to crossing or merging vehicles. Yield the right-of-way to any cross traffic that is close enough to cause conflict.

Large trucks and buses have large blind spots to the sides, the rear, and the front. These areas are referred to as "No zones." Drivers of smaller vehicles should avoid lingering in these areas because they will be invisible to the truck driver and may also restrict the truck driver's ability to stop or maneuver safely.

Drivers are required to stop for a stopped school bus when driving on a two-lane road, regardless of which direction they are traveling.

Before you return to your driving lane, be sure you are not dangerously close to the vehicle you have just passed. One way to do this is to look for the vehicle in your inside rearview mirror.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow and black. This sign tells drivers that a lane is ending and that they should prepare to allow traffic to merge safely.

If your vehicle leaves the roadway, hold the steering wheel firmly, release the gas pedal, and gently apply the brakes. Wait until your speed has reduced, check the traffic, and look for a place to safely return to the roadway by merging back into traffic. Overcompensating by jerking the wheel to return to the roadway can cause you to lose control of your vehicle or may cause your car to go into other lanes of traffic.

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.

Backing up is always dangerous because it is hard to see behind your vehicle. Use extra caution when backing up.

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.
