Sample Drive Test Iowa 2021

Warning signs are normally diamond-shaped and yellow, although orange warning signs are used in work areas. Such signs warn that you are approaching a hazardous location or an area where special rules apply.

To drive quickly, pass, or turn left, use the left lane. Use the right lane when driving more slowly than surrounding traffic, entering the road, or turning right.

Yellow lines separating lanes of traffic indicate that traffic is moving in opposite directions. Double solid lines indicate that passing is not permitted from either direction.

At a green light, you must give the right-of-way to any vehicle, bicyclist, or pedestrian in the intersection. If a pedestrian begins crossing the street after the traffic signal light starts flashing, wait until they have crossed the street before proceeding.

Driving at night is more hazardous than daytime driving because the lowered visibility makes it difficult to judge speed, distances, and other potential hazards. Increase your following distance to help prevent a potential collision if the vehicle in front of you should stop abruptly. Use your headlights when driving at night, following the rules for proper usage of high beams and low beams.

When driving on wet roads, drivers should increase their following distance.

You may encounter unexpected conditions in a construction zone. For the safety of yourself, other drivers, and construction workers, drive with extraordinary caution.

When driving near heavy trucks, other drivers and highway users must make allowances for the increased stopping distance required by the large vehicles. Drivers of smaller vehicles should remain in locations where they can be seen by the driver of the large vehicle and where their view of traffic is not blocked by the vehicle.
