What is the proper rule for using high beams?
Correct answer: Use them whenever it is both safe and legal.
Answer options
- AUse them whenever it is both safe and legal Correct
- BDim them once you are within 100 feet of another vehicle
- CTurn them on if an oncoming driver fails to dim
Why
High beams let you see much farther down a dark road, so use them when conditions and the law permit. Lower them well before you get close to other traffic, such as when an approaching vehicle is within 500 feet, and never answer another driver's glare with your own high beams.
