Delaware CAR DMV Practice Test 11

Drivers of trucks, buses, vans, and any vehicles pulling campers or trailers may not be able to see you if you are driving directly behind them. Increase your following distance when driving behind one of these vehicles. Additionally, large vehicles can block your view of the road, so increase your following distance to look around the sides of the vehicle and see the road ahead.

On cold, wet days, shaded spots on a roadway can become icy. Shaded areas often freeze before, and thaw out after, the rest of a road.

Yellow lines mark the center of a road used for two-way traffic. A solid yellow centerline indicates that drivers may not cross the line to pass. A broken yellow centerline indicates that drivers may cross the line to pass, but only if passing would not interfere with traffic.

Drivers must slow down when approaching an intersection. If a clear view of cross traffic is obscured, a driver should come to a stop and inch forward until they can see clearly in both directions.

If two vehicles arrive at the same time to an intersection that has stop signs on all corners, the vehicle to the right has the right-of-way.

Your vehicle's stopping distance increases as your speed increases. When driving at high speeds, it is important to look well ahead of your vehicle to allow yourself space to safely react to hazardous situations.

This sign warns of a reverse curve in which the road curves to the right, then to the left.

Transit buses, school buses, and vehicles carrying hazardous materials are required to stop at all railroad tracks before crossing, regardless of the presence of a train. Be prepared to stop at all railroad crossings when following one of these vehicles.

Pentagonal signs indicate that you are in or are approaching a school zone and/or school crossing. Be aware of children when driving near a school zone and follow posted speed limits.

Instructions given by police officers directing traffic always override posted traffic signals and signs. Follow the officer's instructions.

Slow down and proceed with caution if you see animals that are standing near the roadway. They may unexpectedly bolt or change direction at the last moment. Some animals travel in packs, so there may be more animals just out of sight that are also near the road.

Hydroplaning is caused by driving too fast on a wet road. Slow down when driving on wet pavement to prevent hydroplaning.

If a road has four or more lanes with two-way traffic, drive in the right lanes unless you are passing or turning left. If you are on an interstate highway and are driving below the speed of the flow of traffic, use the right lane.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns drivers that another road crosses the highway ahead.

When approaching a railroad crossing, you must look, listen, slow down, and prepare to stop. Let any trains pass before you proceed.

This sign indicates that the road may be slippery when wet. Exercise caution when driving on a slippery road.

You should avoid looking toward the bright lights of an oncoming vehicle by glancing toward the right side of the road. After looking briefly toward the side of the road, continue looking ahead to check on the position of the other vehicle.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns that you are leaving a separated one-way highway and will soon be driving on a two-way highway.

It can be hard to judge the speed of oncoming vehicles. They do not always seem to be coming as fast as they really are. Always be sure you can safely change lanes when passing on a two-lane street. If you are not sure of an oncoming vehicle's speed, wait to pass until the oncoming vehicle has passed and you are sure there is enough space for you to change lanes safely.

The term “distracted driving” refers to driving while anything takes your eyes, hands, or mind away from the task at hand. Distracted driving is the most common contributing factor to reported traffic collisions. Distractions of any sort cause drivers to miss key visual and audio cues needed to avoid a crash.

A round sign always indicates that you are approaching a railroad crossing.

A number of drugs can impair your ability to drive, including depressant medications like tranquilizers and sedatives; over-the-counter cough syrups, cold tablets, and allergy medications (which may contain impairing substances like alcohol, codeine, or antihistamines); and illegal drugs.

Signs with a red circle and diagonal line over a black symbol indicate that the action represented by the symbol is prohibited. In this case, the sign indicates that left turns are prohibited.

When changing lanes, glance over your shoulder to check for traffic in your blind spot. You may need to look several times before changing lanes. You must keep track of what traffic is doing in front of you as well as what traffic is doing in the lane next to you.

If you come across a "No passing zone" sign, it is not legal to pass in the indicated area. You are likely driving in an area with restricted visibility where it would be unsafe to pass another vehicle.

Regulatory signs provide notice to road users of traffic laws that must be obeyed. This sign tells drivers that it is prohibited to make a U-turn.

When a steady yellow light appears on a traffic signal, you should prepare to stop. If you are already within the intersection, you should clear the intersection as quickly as possible.

If you are being followed too closely by another driver, merge into a different lane. If there is no lane available for merging, wait until the road ahead is clear and slowly reduce your speed. This will encourage the tailgater to drive around you.

This sign is displayed on slow-moving vehicles.

When stopped for a train at a railroad crossing that has more than one track, wait to proceed until the passing train is well down the track. A train may be approaching on the second track and blocked from your line of sight by the passing train.
