Iowa DOT Permit: Signs & Signals Practice Test

Not quite. The answer is keep right of the divider.

The road ahead will be split into two separate roadways by a median or divider. Keep right.

Not quite. The answer is Stop if it is safe to do so.

A steady yellow traffic light is a warning that the traffic light will soon turn red. You should try to stop if it is safe to do so. But do not stop suddenly; always consider the vehicles behind you before you brake. If you cannot stop safely, proceed with caution through the intersection.

Not quite. The answer is No.

This sign indicates that parking is prohibited here between 8:30 a.m. and 5:30 p.m.

Not quite. The answer is a yield sign ahead.

This sign indicates a yield sign ahead. Be ready to slow down and yield to other vehicles already on the road.

Not quite. The answer is in work zones.

Most US states impose additional penalties for certain traffic violations in work zones under certain conditions, although the conditions and additional penalties vary from one state to another. This sign informs drivers that fines for exceeding the posted speed limit in work zones are doubled.

Not quite. The answer is make a U-turn.

This is a U-turn sign. This sign allows you to make a U-turn if it is safe to do so.

Not quite. The answer is travel in the same direction is permitted on both sides of the line, but crossing the line is prohibited.

A double solid white line marks the edge of a traffic lane where travel in the same direction is permitted on both sides of the line, but crossing the line is prohibited. Double solid white lines are often used on freeways to separate a high-occupancy vehicle (HOV) lane from other lanes.

Not quite. The answer is A no-passing zone for all vehicles

This sign indicates a no-passing zone for all vehicles (buses, trucks, passenger cars, etc.).

Not quite. The answer is A steep descent ahead; drivers may need to shift into a lower gear.

This sign warns that there is a steep descent ahead. Check your brakes before starting the descent. Use low gear to reduce wear on your brakes even if your vehicle has an automatic transmission.

Not quite. The answer is Yes, you must signal for 300 feet where the speed limit exceeds 45 mph, and 100 feet everywhere else.

In Iowa, you are legally required to signal for at least 100 feet where the speed limit is 45 mph or less. You must signal for at least 300 feet where the speed limit exceeds 45 mph. (Note that at 45 mph, your vehicle will travel 100 feet in just 1.5 seconds. Note also that the laws on this are different in some other states. When traveling out of state, always check the local traffic laws.) You must signal even if you cannot see pedestrians or other vehicles. The most dangerous vehicle on the road could be the one you don't see. [Turn Signals, Proper Turning Techniques, 3. Safe Driving Tips, Iowa Driver's Manual],

Not quite. The answer is Farm machinery may be crossing the road.

This warning sign indicates to the driver that farm equipment may be crossing the road. Be ready to slow down for slow-moving equipment.

Not quite. The answer is slow down.

A flashing yellow light is used on some tow trucks and slow-moving vehicles. It warns you to slow down. (Note that this is different from the flashing yellow lights at some intersections. A flashing yellow light at an intersection means that you should slow down and proceed with caution through the intersection.)

Not quite. The answer is the road ahead curves to the right and then to the left.

This sign indicates a double curve ahead. The road ahead curves to the right and then to the left. (If there were a triple curve ahead, a winding road sign would be posted instead.) Slow down, keep right, and do not pass.

Not quite. The answer is Leave a vacant lane next to the emergency vehicle if possible; otherwise, prepare to stop.

If possible, leave an empty lane between you and a stopped emergency vehicle with its flashing lights on. If this is prohibited, unsafe, or otherwise impossible, slow down to a reasonable speed and prepare to stop.

Iowa law requires each child under the age of six to be seated in a child safety restraint system.

This sign means that traffic on the road may flow on both sides of the sign.

Not quite. The answer is There is a railroad crossing ahead.

This sign warns of a railroad crossing ahead. Watch out for warning signals and approaching trains.

Not quite. The answer is A speed zone is ahead; prepare to reduce your speed to 45 mph.

The larger sign tells you that a speed zone is ahead. The smaller sign indicates what the speed limit will be. In this case, the speed limit will decrease to 45 mph ahead. Prepare to slow down so you won't exceed that speed limit.

Not quite. The answer is a work zone sign.

Construction or work zone signs are used to notify drivers of unusual or potentially dangerous conditions on or near the traveled way. All temporary signs in work zones have black letters or symbols on an orange background.

Not quite. The answer is a slow-moving vehicle.

A reflective triangular orange emblem on the rear of a vehicle identifies it as a low-speed or slow-moving vehicle, which is typically defined as a motor vehicle whose top speed is no greater than 25 mph. Slow-moving vehicles include farm vehicles and roadway maintenance vehicles. If you approach one of these vehicles, slow down and proceed with caution.
