25. When turning or changing lanes, you must:

Always signal your intentions, even when no visible traffic is present.

Signal only if there is visible traffic.

Signal only when driving at night.

Signal only when driving in heavy traffic at night.

Always signal your intentions when changing lanes, turning, or pulling away from a curb. Do not allow yourself to become lazy and form the bad habit of not following this law.

26. You are required to stop your vehicle:

At any intersection where a police officer orders you to stop.

Where there is a red traffic light.

Both of the above.

You must come to a complete stop at a steady or flashing red traffic light. You must always obey instructions given by officers directing traffic, regardless of any posted signs or traffic signals.

27. What does alcohol do to your driving skills and judgement?

It helps driving skills but harms your judgement.

It harms both driving skills and judgement.

It has no effect on either driving skills or judgement.

It has no effect on judgement but it harms driving skills.

Alcohol negatively affects many skills needed for safe driving, including your reaction time and ability to see clearly. It can also harm your judgment of speed and distance, lower your inhibitions, and make you more prone to taking chances.

28. When taking any medicine, you should:

Consult your doctor about the effects before driving.

Have someone follow you home.

Keep your window open and drive more slowly.

Legal medications, both prescription and over-the-counter, can potentially impair your ability to drive. Always consult with your doctor or pharmacist if you have questions about how a particular drug or drug combination will affect your ability to drive. You should particularly make a point of talking with your doctor if they give you a prescription for a tranquilizer or sedative.

29. To be safe when crossing a railroad, you should:

Look both ways, but only when the red light is flashing.

Listen, look both ways, and then proceed if it is safe to do so.

Cross especially quickly when a train is approaching.

Quickly pass under any lowering gates.

Railroad crossings are always dangerous. Drivers should look and listen for an approaching train coming from either direction before proceeding across the tracks. Watch for signals indicating an approaching train and never proceed until you are certain it is safe to do so.

30. According to the Iowa Implied Consent Law:

An arrested driver may be asked to submit to a chemical test to determine the alcohol content of their blood.

Refusal to submit to chemical testing will result in a driver's driving privileges being withdrawn.

Both of the above.

Under Iowa's Implied Consent Law, any peace officer may ask you to submit to a breath, urine, or blood test if the officer feels you may be driving under the influence of alcohol or drugs. This applies to both resident and non-resident drivers. If you take the test and fail, or you refuse to take the test, your license can be taken away on the spot.
