✍️ Sample IA DMV Questions & Answers
1. What does a white sign with a red circle and diagonal line through a left turn arrow mean?
A red circle with a diagonal line is a prohibition symbol. When placed over a left turn arrow, it means left turns are not permitted at that location.
2. What is the safest action when you are being tailgated on an Iowa highway?
Gradually slow down and allow the tailgater to pass by moving to the right; sudden braking increases the risk of a rear-end collision.
3. When driving in heavy fog in Iowa, what should you use instead of high-beam headlights?
Low beams or fog lights should be used in fog because high beams reflect off fog particles and reduce visibility.
4. What does a flashing yellow traffic light mean?
A flashing yellow light means slow down, yield to cross traffic and pedestrians, and proceed with caution.
5. In Iowa, when is it legal to make a right turn on red?
Iowa allows right turns on red after a complete stop, yielding to all traffic and pedestrians, unless a 'No Turn on Red' sign is posted.
6. What document must Iowa drivers carry in their vehicle as proof of insurance?
Iowa accepts either a physical insurance card or electronic proof displayed on a mobile device as valid proof of financial responsibility while driving.
