A solid yellow line indicates it’s unsafe to pass into oncoming traffic. A single dotted yellow line or a solid yellow line with a dotted line on your side of traffic indicates that it’s a safe move.

Tunnels, bridges and viaducts can obstruct your view. If you see any up ahead, wait until you have passed them to consider a move. Do not attempt to pass a slow moving car if you’re driving on a hill or curve because you’ll have limited vision. Wait for a long stretch of flat road. Be aware of driveways and other entrances where cars may unexpectedly come from. If the weather is rainy, foggy or snowy, consider staying in your lane as these types of conditions can cause you to slip or they can make it more challenging to see ahead. Check your surroundings for animals, like deer, that can run into the middle of the road.

Establish there is no oncoming traffic that will come within 200 feet (0. 061 km) of you in the passing lane. Do not pass if you can’t see . 25 miles (0. 40 km) ahead. Look at your rear-view and side mirrors for traffic coming from behind you right before you move into the opposite lane to pass. Then check for oncoming traffic once again.

You’ll have to increase your speed up to 20 miles (32 km) to pass, so be sure you’re aware of the speed limit where you are. Be aware that speed limits can drop dramatically, up to 30 miles (48 km), along some country roads upon arriving in a town.

Use the two-second rule. Count one thousand one, one thousand two after the car in front of you has passed a marker of some kind to be sure you have enough space. A sign, tree or lamppost works as a marker.

Avoid being aggressive with your speed and give yourself plenty of time and space between the vehicle. Don’t slam on the gas to safely arrive in front of the slow car.

Always keep an eye on the vehicle you’re passing to be sure they don’t speed up or move in an unexpected way. Keep both hands on the wheel the whole time. Be on alert.

Smoothly cross back into the lane. Maintain your desired speed without exceeding the limit. Glance in your rear-view to check the distance of yourself and the car you passed.
