P A G E 4 1.1 WHO NEEDS AN IOWA DRIVER’S LICENSE? In Iowa, anyone operating a motor vehicle, motorcycle, or moped on public roads is required to have a permit or license.
P A G E 40 C H A P T E R 4 MANUAL TR ANSMISSION For vehicles with a manual transmission, shifting gears regulates the range of speeds the vehicle may travel in.
The faster your vehicle is going, the more distance it will take to turn, slow, or stop. For example, a vehicle traveling 60 mph will travel 3 times further than a vehicle traveling 30 mph before coming to a stop. (See figure 4.1) In the event the speed limit is not posted, the following general limits have been set: • 20 mph in any
crash. Try to drive with the general traffic flow on any road. On the interstate system there is a minimum speed of 40 mph. Vehicles that cannot go at least that fast under normal conditions are not allowed on the interstate. 4.6 STEERING GRIPPING THE WHEEL To reduce the risk of injury from front airbags and best maintain control of your vehicle, use a
a stronger position to deal with other people’s driving choices. Leave plenty of space between you and the car in front. Always wear your seatbelt to protect you from being thrown from the car in a crash. 2. Be aware of your surroundings — pay attention. Check your mirrors frequently and scan conditions 20 to 30 seconds ahead of you. Keep your eyes moving.
• Pass the knowledge test. • Show that you’ve successfully completed an Iowa-approved driver’s education course (if you are under 18).
P A G E 58 C H A P T E R 5 5.10 SHARING THE ROAD WITH MOTORCYCLES • Respect the vehicle space of a motorcycle and its position in traffic.
