Head on approach and headlight failure — Massachusetts Permit Test
Head on approach and headlight failure on the Massachusetts permit test — 3 rules, each with the reason behind it and a question on it while it is fresh.
The rules
If a vehicle is driving toward you head on in your lane, slow down, pull to the right, and sound your horn.
Right is where the road gives you room and where the other driver is most likely to correct toward.
If a vehicle is driving toward you head on in your lane: • Slow down and pull to the right. • Sound your horn to alert the other driver.
If your headlights suddenly go out, turn on your parking lights, emergency flashers, or turn signal.
Anything lit is better than nothing. The point is to be visible while you get off the road.
Turn on your parking lights, emergency flashers, or turn signal.
After the headlights fail, try the headlight switch a few times and pull off the road as quickly as possible with the flashers on.
Sometimes the switch brings them back. Either way the car needs to be off the road.
Pull off the road as quickly as possible and leave your emergency flashers on.
On the test
What should a driver do when a vehicle approaches head on in their lane?
Slow down, pull to the right, and sound the horn. Right is where the road gives you room and where the other driver is most likely to correct toward. Massachusetts Driver's Manual, p.125: “If a vehicle is driving toward you head on in your lane: • Slow down and pull to the right. • Sound your horn to alert the other driver.”
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.
