About this Written Test Study Guide
If you’ve ever lived in another state or even just flipped through the driver’s handbook for a few different states, you’ll probably notice that for the most part the information is the same.
That’s because being a safe driver is universal. It comes down to:
- Eliminating distractions while driving.
- Staying alert and anticipating hazards before they occur.
- Knowing how to react in emergency situations.
- Being courteous and knowing how to share the road with other cars, motorcycles, trucks, bicyclists, and pedestrians.
- Avoiding the use of alcohol or drugs if you are going to be driving.
Our researchers have been busy analyzing the driver’s handbooks and written exams across the country, and we’ve compiled this study guide to highlight the important, potentially confusing, and common topics that we’ve found.
Read through the universal topics and road signs, and be sure to check out the section for your state for your state too.
Additionally, you’ll find a printable version of this DMV cheat sheet for your state for free. Each PDF includes handbook information and a road sign study guide to help you prepare for your test. Each page also includes a “notes” section that you can use while you read through the official driver handbook.
Remember, passing the written test comes down to study and preparation. You’ve got this!

Universal Driver’s Handbook Study Guide
These are the topics that are pretty much universal in every state. Study these to get familiar with things like right-of-way rules, stopping distance, and reacting to emergencies.
When should you give up your right-of-way?
Always yield your right-of-way when it will prevent a collision or an unsafe situation.
Where should you stop when you come to a crosswalk with pedestrians crossing?
When you come to a crosswalk, stop before the line.
Always yield to pedestrians who are entering or are already in a crosswalk before crossing through a crosswalk.
What should you do at an uncontrolled intersection (no signs, no signals)?
- Slow down and be ready to stop.
- Yield to pedestrians.
- Yield to traffic or bicycles that arrive first.
- If traffic arrives at the same time, yield to the vehicle on the right.
Who has the right-of-way at a T intersection?
Yield to vehicles and pedestrians on the through-street, they have the right-of-way.
Who has the right-of-way when you are making a left turn?
Yield to oncoming traffic. Keep your wheels pointed straight when waiting to make a left turn. In the event you are hit from behind, this will help prevent your vehicle from rolling into oncoming traffic.
What are the right-of-way rules at intersections controlled by stop signs?
- Yield to pedestrians.
- The vehicle to arrive first, goes first.
- If vehicles arrive at the same time, yield to the vehicle on the right.
Which direction does traffic move in a roundabout?
Traffic moves counter-clockwise, or to the right of the island, in a roundabout.
What is the proper way to use a roundabout or rotary intersection?
- Slow down before you reach the roundabout.
- Yield to pedestrians and bicycles.
- Obey traffic signs and lane markings.
- Yield to traffic inside the roundabout.
- Enter the roundabout when there is a gap that allows you to merge safely.
- Do not stop or pass other vehicles in the roundabout.
- Signal to change lanes or exit.
- If you miss your exit, continue around to it again.
Who has the right-of-way on a steep, narrow mountain road with no room to pass?
The vehicle facing downhill must yield to the vehicle facing uphill.
The vehicle facing downhill will have more control when backing up the hill.
The vehicle facing uphill has the right-of-way.
What do the posted speed limit signs indicate?
Speed limits regulate the maximum speed when driving conditions are good.
What are some situations that may require you to drive slower than the posted speed limit?
- In bad weather.
- In poor visibility.
- When driving at night.
- Around children, schools, and parks.
- When towing a vehicle.
- In areas where you can’t see the road ahead (blind intersections, curves, corners)
- Near wildlife crossing areas.
What are the main factors that determine how much time and distance you will need to stop?
- Perception time: how long it takes for you to perceive a hazard. The average perception time for an alert driver is ¾ second to 1 second.
- Reaction time: how long it takes for you to react to a hazard. The average driver has a reaction time of ¾ second to 1 second.
- Braking distance: how far your vehicle needs to come to a complete stop.
Total stopping distance also depends on road conditions, tire conditions, brake conditions, vehicle weight, and speed.
How does total stopping distance and force of impact change as you increase your travel speed?
Doubling your speed from 20 to 40 mph, increases your braking distance and force of impact by 4.
Tripling your speed from 20 to 60 mph, increases it 9 times.
Quadrupling your speed from 20 to 80 mph, increases it by 16 times.
How can you identify hazards and avoid last minute maneuvers?
- Scan the road at about 10 to 15 seconds ahead of your vehicle to spot hazards early.
- About 1 block in the city, or about ¼ mile on the highway.
- Use your mirrors to scan what is happening on the sides of and behind your car.
- Scan nearby lanes, oncoming lanes, and the sides of the road to spot hazards before they become a problem.
- Don’t follow other vehicles too closely.
- Avoid fixating on the vehicle in front of you.
- Look both ways at intersections even if you have a green signal. Look left, right, and left again.
- Don’t remain in another vehicle’s blind spot for too long.
- Keep space between your vehicle and vehicles parked along the side of the road.
- Check around your vehicle when backing up. Do not depend on your mirrors alone. Turn your head and body so you can look out of the rear window.
What is a good following distance rule to follow?
Use the 3 second rule when following other vehicles.
When the vehicle ahead of you passes a certain point, count: one-one-thousand, two-one-thousand, three-one-thousand, etc. If you pass the point before you finish counting, increase your following distance.
Certain situations like heavy traffic or poor conditions may require a longer following distance.
NOTE: Check out your state’s recommendations on this topic.
What should you do if a vehicle cuts you off?
Remove your foot from the gas. This allows you to create space without slamming the breaks or swerving dangerously.
