BDifficulty 2/5

If headlights are aimed too low, how can this affect obstacle detection at night?

Correct answer

You may detect them later and have less time to respond.

They illuminate a shorter area ahead and you may detect an obstacle later, leaving less time to respond. This does not mean the driver’s reaction time itself increases. Adjust headlights for manufacturer specifications and load, also avoiding an excessively high aim that dazzles others.
