Truck no zones — Delaware Permit Test

Truck no zones on the Delaware permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.

The rules

In general, trucks take slightly longer than cars to stop because of their size.

A car that cuts in and brakes ahead of a truck asks it to stop in a space it cannot.

In general, trucks take slightly longer than cars to stop because of their size.

Delaware Driver Manual, p.103

When following a truck, allow at least 4 seconds between your vehicle and the truck, out of its rear blind spot.

A car tailgating a truck is hidden from its driver and cannot see the traffic ahead.

Allow at least four seconds between your vehicle and the truck, and remember that you too cannot see, and plan ahead if you follow too closely.

Delaware Driver Manual, p.103

Trucks have large blind spots on both sides; a truck driver cannot see you while you drive in them.

If the truck driver must change lanes quickly, a car hidden at its side is hit.

When you drive in these blindspots (No-Zone) for any length of time, the truck driver can’t see you.

Delaware Driver Manual, p.104

Truck drivers sometimes swing wide to the left to make a right turn.

A driver who sees a truck move left may think it is turning left and pull up on its right.

Truck drivers sometimes need to swing wide to the left in order to safely negotiate a right turn.

Delaware Driver Manual, p.104

Do not cut in between a turning truck and the curb or shoulder on its right; it raises the chance of a crash.

A car in the gap on the right is crushed when the trailer swings back toward the curb.

Cutting in between the commercial vehicle and the curb or shoulder to the right increases the possibility of a crash.

Delaware Driver Manual, p.104

Never try to cross behind a truck that is preparing to back up.

Most commercial vehicle crashes happen while backing, and a car behind the truck is in its blind spot.

Sixty-six percent of all commercial vehicle crashes are while backing; therefore, never try to cross behind a truck which is preparing to back up.

Delaware Driver Manual, p.104

On the test

Compared with a car, how long does a truck generally take to stop?

Slightly longer. A car that cuts in and brakes ahead of a truck asks it to stop in a space it cannot. Delaware Driver Manual, p.103: “In general, trucks take slightly longer than cars to stop because of their size.”

How this works

Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.

You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.

Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
