IA DMV Safe Driving Techniques — Questions and Answers
Question 1: What is the recommended following distance in Iowa under normal conditions?
- 3 to 4 seconds (Correct answer)
- 1 second
- 2 seconds
- 5 seconds
Correct answer: 3 to 4 seconds
Iowa recommends a 3 to 4 second following distance under normal driving conditions, increasing in poor weather or when following large vehicles.
Question 2: When driving in heavy rain in Iowa, what should you do?
- Reduce speed, turn on low-beam headlights, and increase following distance (Correct answer)
- Maintain normal speed and use high beams
- Pull over immediately regardless of conditions
- Drive faster to get through the rain quickly
Correct answer: Reduce speed, turn on low-beam headlights, and increase following distance
In heavy rain, reduce speed to prevent hydroplaning, use low beams for visibility, and increase following distance because wet roads increase stopping distances.
Question 3: What should an Iowa driver do when approaching a school bus with flashing amber lights?
- Prepare to stop as the bus is about to stop and load or unload children (Correct answer)
- Stop immediately
- Pass the bus quickly before it stops
- Honk to alert the bus driver
Correct answer: Prepare to stop as the bus is about to stop and load or unload children
Flashing amber lights on a school bus indicate it is slowing and preparing to stop. Drivers should prepare to stop as the lights will soon change to flashing red.
Question 4: In Iowa, what is the proper action when your vehicle starts to skid on ice?
- Ease off the gas and steer in the direction you want to go (Correct answer)
- Brake hard and turn the opposite direction
- Accelerate to regain traction
- Shift to neutral and coast
Correct answer: Ease off the gas and steer in the direction you want to go
When skidding, take your foot off the gas and steer gently in the direction you want the vehicle to go. Avoid braking hard, which can make the skid worse.
Question 5: What should you do if your headlights suddenly go out while driving at night in Iowa?
- Slow down, activate hazard lights, and safely pull off the road (Correct answer)
- Continue driving using parking lights
- Speed up to reach the nearest exit quickly
- Flash your high beams repeatedly
Correct answer: Slow down, activate hazard lights, and safely pull off the road
If headlights fail, immediately slow down, turn on emergency flashers to remain visible, and carefully pull off the road to a safe location.
Question 6: When merging onto an Iowa interstate highway, what is the correct technique?
- Use the acceleration lane to match the speed of traffic, then merge smoothly (Correct answer)
- Stop at the end of the ramp and wait for an opening
- Merge at whatever speed you are traveling
- Always force your way into traffic since merging vehicles have the right of way
Correct answer: Use the acceleration lane to match the speed of traffic, then merge smoothly
The acceleration lane is designed to allow merging drivers to reach the speed of highway traffic before smoothly entering the travel lanes.
