Final answer:
Yes, you are required to lower your high beams when an approaching car is within 500 feet to prevent blinding the other driver and to maintain road safety.
Step-by-step explanation:
When driving at night, it is required by law to lower your high beams when an approaching car is within 500 feet. This is to ensure both you and the other driver can see clearly without being blinded by the lights. This safety precaution helps to prevent accidents caused by temporary blindness or distraction due to the bright lights of high beams.
