Automatic Failure: 7 Common Mistakes to Avoid on Your Nevada Driving Test

You've studied the handbook, passed your permit test, and logged your 50 hours of practice. The final step between you and the freedom of a Nevada driver's license is the road test. While the test is designed to assess your overall driving competence, there are certain critical errors that are considered so dangerous they will result in an immediate, automatic failure.

Knowing what not to do is just as important as knowing what you should do. Many capable student drivers fail their first test not because they lack skill, but because of a single, preventable mistake made under pressure. This guide highlights the seven most common errors that lead to automatic failure, helping you stay mindful, prepared, and successful on test day.

1. Examiner Intervention

This is the most straightforward reason for an automatic fail. The DMV driving examiner is there to observe, not to co-pilot. If at any point the examiner has to physically intervene to prevent a dangerous situation, your test is over.

• What it looks like: The examiner has to grab the steering wheel to prevent you from drifting into another lane or hitting the curb, or they have to use a brake (if the vehicle is equipped with one on the passenger side) to avoid a collision.
• How to avoid it: This all comes down to control and awareness. Maintain a firm grip on the wheel, be aware of your vehicle's position within the lane, and always scan ahead to anticipate potential hazards. Never drive so close to an object or another car that it forces the examiner to react. Their intervention means you lost control of the situation.

2. Disobeying Critical Traffic Signs and Signals

This is a classic and frequent cause of failure. The core purpose of the test is to see if you can follow basic traffic laws. Ignoring a major traffic control device is a clear sign you are not ready to drive alone.

• What it looks like:
  • Running a red light: Not stopping before the white line while the light is red.
  • Not coming to a complete stop at a stop sign: This includes "rolling stops" where the vehicle's wheels never fully cease their rotation. You must come to a full and complete stop.
  • Ignoring a "Yield" or "Do Not Enter" sign.
• How to avoid it: Be present and focused. When approaching an intersection, identify the type of control (light, sign, or uncontrolled) well in advance. Verbally announce it to yourself if it helps: "Okay, red light, I'm stopping." For stop signs, come to a definitive stop and count "one-one thousand, two-one thousand" before proceeding.

3. Failure to Yield the Right-of-Way

Right-of-way rules are designed to prevent crashes. Failing to yield properly demonstrates a critical lack of understanding of traffic safety.

• What it looks like:
  • Pulling out in front of cross-traffic, causing other drivers to brake suddenly or swerve.
  • Not yielding to pedestrians in a crosswalk.
  • Merging onto a street or highway and cutting off an approaching vehicle.
  • Failing to yield to an emergency vehicle with its lights and siren active.
• How to avoid it: Be patient and defensive. The simple rule is: if you are unsure, yield. Never assume another driver will slow down for you. Always make eye contact with pedestrians and ensure they have cleared your path before proceeding.

4. Unsafe or Improper Lane Changes

Changing lanes is a multi-step process that requires precision and awareness. Messing up any part of it can be grounds for failure.

• What it looks like:
  • Changing lanes without signaling first.
  • Changing lanes without performing a head check (looking over your shoulder) to check your blind spot.
  • Drifting into another lane without intending to.
  • Cutting too closely in front of the car you just passed.
• How to avoid it: Practice the "Signal, Mirror, Over-the-shoulder, Go" (SMOG) method until it's second nature. Signal your intention, check your rearview and side mirrors, physically turn your head to check your blind spot, and only when it's completely clear, smoothly move into the adjacent lane.

5. Dangerous Speeding or Driving Excessively Slow

Your ability to maintain a proper, safe speed is constantly being evaluated. This is a test of judgment, not a race.

• What it looks like:
  • Exceeding the speed limit, especially in a school zone or construction zone, which is often an instant fail.
  • Driving significantly slower than the flow of traffic for no reason (e.g., going 20 mph in a 40 mph zone). This can be just as dangerous as speeding.
• How to avoid it: Be aware of the posted speed limit at all times. As you enter a new street, actively look for a speed limit sign. Adjust your speed based on conditions—slow down in rain or heavy traffic—but when conditions are clear, try to stay near the posted limit.

6. Lack of Vehicle Control

The examiner needs to see that you are the master of the vehicle, not the other way around. This includes both major and minor maneuvers.

• What it looks like:
  • Forcefully striking a curb during a turn or while parking. A light tap might only cost you points, but a hard hit can fail you.
  • Jerky acceleration and braking that makes the ride uncomfortable and shows a lack of fine motor control.
  • Inability to keep the car straight when backing up.
  • Fumbling with vehicle controls like windshield wipers or headlights.
• How to avoid it: Practice, practice, practice. Spend time in an empty parking lot getting a feel for the car's dimensions, its turning radius, and the sensitivity of the gas and brake pedals.

7. Creating a Generally Hazardous Situation

This is a catch-all category for any action that demonstrates poor judgment and puts you, the examiner, or other road users in danger.

• What it looks like:
  • Following the car in front of you too closely (tailgating).
  • Making a turn from the wrong lane.
  • Showing extreme hesitation that confuses other drivers, such as stopping in the middle of a road for no reason.
• How to avoid it: Drive with confidence, but not aggression. Be predictable. Use the "3-second rule" for following distance. Think several steps ahead. Instead of just looking at the car in front of you, look past it to see what traffic is doing farther down the road.

A Final Word on Nerves

It's natural to be nervous, but don't let anxiety be the reason you make one of these mistakes. Get a good night's sleep before your test. Eat a healthy meal. On test day, take deep breaths to calm yourself. Remember, the examiner isn't trying to trick you; they simply want to verify that you are a safe, responsible driver. By avoiding these common pitfalls, you can prove to them—and to yourself—that you are ready for the road.
