How to Pass a Semi

With the record numbers of vehicles on the highways today, we all have to do what we can to share the road safely. When driving around semi trucks, for example, it helps to understand their reduced visibility and maneuvering capability. This is important information to know when trying to pass a semi truck.

Instructions

1. Let the semi get up to speed. Trucks take longer to gain speed than cars do. Taking off from a stoplight, it can take a truck twice as long to achieve cruising speed than a car. Since you don't know how fast the truck driver is planning to travel, don't pass the truck until it reaches a stable driving speed-the driver may intend to travel faster than you do.

2. Turn on dim headlights if you don't have running lights. (Don't use brights, as they create a blinding glare in the large side mirrors as you pass the truck.) Cruise near the center line, at least two car lengths behind the semi, so the driver can see you. Be mindful of oncoming traffic.

3. Use your turn signal to show you're about to pass. Allow it to flash two or three times before you pull into the left lane to go around the semi.

4. Pass when you have plenty of time, in a passing zone. Don't try to sneak around trucks (or any vehicle) in a no passing zone. This can prove to be a fatal error.

5. Accelerate smoothly and move past the semi at a brisk, but safe, pace. Don't hover near the side of either truck or trailer. Big trucks have large blind spots. A driver can look in the mirror, not see you, and change lanes into the side of your vehicle by accident.

6. Return to the driving lane only after you can see the entire front end of the semi truck in your rear-view mirror. If you can only see the front grille, you're too close. Pulling too closely in front of a semi after you pass can be dangerous. If you came to a sudden stop, such as if a deer ran in the road, the semi would be unable to stop before hitting your car.

Tips & Warnings

• Look in the side mirrors on the semi as you pass a truck. If you can't see the driver's face, the driver can't see you.

• Never pass any vehicle, including semi trucks, on the right. Drivers expect slower moving traffic in the right hand lanes. Even when they glance in the mirror and see you behind them, they won't anticipate your speed and may change lanes unexpectedly.

• Never dart in and out of traffic. Move smoothly and use your signals. The more predictably you drive, the less likely you'll be involved in a traffic accident. A little common courtesy goes a long way--please share the road with others.
