Did you know that approximately ¼ of all vehicles on Utah roads are large trucks? Nationally, over 75 percent of auto vs. truck crashes are caused by negligent driving on the part of the auto driver. By understanding just how massive these trucks are, how large their blind spots are, and how much room they need to operate and come to a stop, our roads and highways can be a much safer place for everyone.


Now that you’ve seen the Truck Smart presentation, take the quiz below to see just how Truck Smart you are. Next, complete the form so the assignment can be sent to your teacher with your score.

A typical fully loaded tractor-trailer weighs:

√ Correct! And it is not uncommon to even see heavier loads on the road.

A typical passenger vehicle traveling at 65 mph under ideal conditions takes:

√ Correct!

A fully loaded tractor-trailer traveling at 65 mph under ideal conditions takes a minimum of:

√ Correct! And 525 feet is really the minimum it would take a semi to come to a stop. If the weather conditions are bad, such as raining or snowing, it will take even longer. Tanker trucks also take much longer and farther to come to a stop due to the surge of liquid.

Total stopping distance for a passenger vehicle is a combination of what three things?

√ Correct! And the fourth factor semi-trucks have is brake lag.

It is okay to pass a snowplow pushing snow, as long as you have four-wheel drive.

√ Correct! It is NEVER okay to pass a snowplow.

The rear blind spot behind a semi-truck extends approximately 200 feet.

√ Correct!

You know you are not in a blind spot if you can see a truck's side mirrors.

√ Correct! It is not enough to just see the side mirrors, but you need to see the driver's face in the side mirrors. If you can see the driver's face in the side mirrors, then you know that they can see you.

How many car lengths should you allow before pulling in front of a truck?

√ Correct! The rule is one car length for every 10 miles per hour, but the easiest thing to do is look for the two headlights in your rearview mirror, or steer clear.

It is illegal to pass a truck pulling multiple trailers.

√ Correct! Even if there are multiple trailers, you still want to pass and get in front where the driver can see you (assuming conditions are safe). Just remember that it will take you longer.

Trucks often pull into the left lane to let traffic pass on the right when making right turns.

√ Correct! Trucks leave that right lane open for their trailer to clear the corner. If you see a truck turning right, just wait until it gets out of your way.

Trucks and buses require more distance and time to stop and maneuver than cars do.

√ Correct!

Truck drivers have better visibility because they sit up so high.

√ Correct! Truck drivers may sit up higher, but they have huge blind spots.

It is safe to draft or tailgate large trucks or buses to save gas.

√ Correct! It is NEVER safe to draft or tailgate behind a semi-truck.

After passing a truck and returning to the lane in front of the truck, do not slow down.

√ Correct!

A semi has more brakes so it can stop faster than a car.

√ Correct! Trucks need substantially more room than you or I do in our passenger cars.

It is legal to stop beyond the white stop line at an intersection as long as you watch for traffic and pedestrians.

√ Correct! It is never okay to stop past the white stop line.
