Answer:
D. Turn only after there is no danger from oncoming vehicles.
Explanation:
A driver waiting to make a left turn when the traffic light turns green should turn only after there is no danger from oncoming vehicles.
Generally, in accordance with the highway traffic laws and regulations, it is important and necessary that when making a left turn even with a green traffic light signal that all drivers should only turn after there is a confirmation of no danger from oncoming vehicles. If this is strictly adhered to by road users such as drivers, there would be a great reduction in the number of road crashes or accidents.
