Final answer:
When you see an oncoming car, you should turn off your high beams 1000 ft away.
Step-by-step explanation:
When you see an oncoming car, you should turn off your high beams 1000 ft away. High beams are designed to provide maximum visibility but can blind other drivers, especially when they are approaching from the opposite direction. By turning off your high beams when you see an oncoming car, you ensure that both you and the other driver have clear visibility on the road.
