Driving at dark with the high beam turned on might:
- Waste electricity.
- Correct answer: Blind (dazzle) other drivers.
- Spoil the battery.
- Impair the driver’s vision.
Why this is the answer
The correct answer in the official bank: Blind (dazzle) other drivers.
The high beam is strong and aimed far ahead, so it can dazzle oncoming drivers, and also drivers ahead of you through their mirrors. A dazzled driver has difficulty seeing the road. So switch to low beam when you approach another vehicle or drive behind it.
