Entering and leaving traffic — Delaware Permit Test
Entering and leaving traffic on the Delaware permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
When you merge with traffic, Delaware's manual says to try to enter at the same speed traffic is moving, using the ramp to build up speed.
A car that rolls onto a fast highway well below the flow of traffic forces drivers behind it to brake or swerve.
When you merge with traffic, try to enter at the same speed that traffic is moving.
Delaware's manual says not to drive to the end of an entrance ramp and stop; if you must wait for space, slow down on the ramp so you have room to speed up before you merge.
A car stopped at the end of a ramp has no room to reach highway speed and may be hit from behind.
If you have to wait for space to enter a roadway, slow down on the ramp so you have some room to speed up before you merge.
On a road with exit ramps, Delaware's manual says to keep up with traffic and not slow down until you move onto the exit ramp.
Braking in a fast lane for an exit still ahead leaves the cars behind closing on a slowing car.
If the road you are traveling has exit ramps, do not slow down until you move onto the exit ramp.
On the test
When you merge onto a high-speed road from a ramp, at what speed should you try to enter?
The speed traffic is moving. A car that rolls onto a fast highway well below the flow of traffic forces drivers behind it to brake or swerve. Delaware Driver Manual, p.124: “When you merge with traffic, try to enter at the same speed that traffic is moving.”
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.
