8 Costly Drive Test Mistakes (And How to Avoid Them)

Written by Steve Lents | Aug 28, 2025 6:00:00 PM

Do you feel solid on practice drives—but worry that one small mistake will sink your score when an examiner is watching? You’re not alone.

Test day pressure is real, and it can turn learned habits (like full stops, mirror checks, or proper lane changes) into point losers. The cost of a misstep isn’t just a score; it can include additional fees, more time off work or school, and another stretch without the freedom a license gives.

At Pacific Driver Education, we understand moments like this. We’re a DMV‑certified school and testing center with certified instructors who know how to teach precise skills that help reduce the pressure associated with the drive test.

Since 2010, we’ve helped thousands of teens and adults build calm, repeatable habits and then, when they’re ready, administer the driving test. That means fewer surprises and a smoother path to “Success.”

This article will break down the most common ways people lose points or fail their driver's test.  It will show you exactly how to prepare so those issues don’t cost you, and explain the results you can expect once you fix them.

By the end, you’ll have the tools that will help you build the necessary habits and next steps to pass your test and drive with confidence.

1. Not Observing Enough 

The Problem

Examiners watch your eyes. Missing mirror checks, skipping a shoulder check, or looking too late at an intersection can cost points fast.

Oregon DMV spells out that examiners look for Situational Awareness
When driving, you must watch for pedestrians, traffic signs, roadway markings, bicylists, and other road traffic, and you must turn your head to check your blind spot before making every lane change. 

Distractions increase the risk; AAA research found distraction was a factor in nearly 6 out of 10 moderate‑to‑severe teen crashes.

How to Avoid It

Work on building a steady scanning routine: mirrors every few seconds, then mirror-signal-shoulder checks for every lane change.

The Oregon Driver Manual tells you to check mirrors and your vehicle’s blind spot by glancing over your shoulder before passing or changing lanes, and to check behind and beside you well before turning while watching for people on bikes in your blind spot.

At intersections, pause and scan to the left, front, and then to the right, deliberately before you roll forward.

Result When Corrected

You will spot hazards sooner, make smoother, more informed decisions, and show the examiner you’re in control.

That confidence will reduce errors that happen when you’re caught off‑guard.

Oregon’s driver's scoring sheet tracks observation, lane usage, and attention, so strong scanning will directly protect your score.

2. Rolling Stops and Traffic‑Signal Violations

The Problem

Rolling a stop or creeping through a red is an automatic failure in many cases.

Oregon’s scoring sheet lists running a red light or stop sign among grounds for immediate failure; the sheet also emphasizes full, legal stops at crosswalks and intersections.

Beyond the test, red‑light running isn’t minor: in 2023, 1,086 people were killed in red‑light–running crashes nationwide.

How to Avoid it

At stop signs, stop behind the line, and use your "front limit reference point" as a guide. Then count “one‑two‑three,” then scan for people and cross‑traffic before moving.

On right‑turn‑on‑red, come to a complete stop and yield to pedestrians first. Treat stale green lights (that have been green for a while) as cautions and be ready to stop.

Result When Corrected

You protect yourself from an instant fail, and your overall score rises because you’re demonstrating legal, predictable behavior at high‑risk points on the route.

Oregon examiners score stops, right‑of‑way, and crosswalk behavior—doing this well checks multiple boxes.

3. Driving Too Fast—or Too Slow—for Conditions

The Problem

Speed mistakes cut points in both directions. Oregon’s drive-test scoring form explicitly lists “Speed — Too fast / Too slow” as graded items.

Examiners are watching how you adjust to traffic, visibility, weather, and road design—not just the number on the sign. 

Big picture, speeding is a major U.S. safety issue: in 2022, 12,151 people died in speeding-related crashes—29% of all traffic deaths.

Oregon’s Basic Speed Rule states that you must drive at a speed that’s “reasonable and cautious for existing conditions,” and you can violate that rule even when you drive below the posted limit if your speed isn’t safe for existing conditions.

Driving much slower than traffic can also create risk; Oregon instructs slower drivers to keep right and, if needed, pull off at the first safe spot to let others pass.

How to Avoid It

Know the posted limit, but drive for conditions—match the flow without exceeding the limit, and slow earlier for rain, fog, curves, hills, and construction zones.

Oregon’s manual highlights variable speed signs that may lower limits during poor conditions; treat these as you would any other speed limit notification.

Keep a generous following gap and look far down the road to avoid last-second braking. If you’re moving slower than normal traffic, stay to the right and use the next safe turnout to let others by.

Result When Corrected

A steady, appropriate pace shows the examiner you can manage risk and traffic flow. You stay clear of Basic Speed Rule violations and eliminate “too fast/too slow” deductions.

When you have your speed under control, your attention is free for scanning, signaling, and situational awareness.

4. Right‑of‑Way Errors

The Problem

Right‑of‑way mistakes cause both test failures and real‑world harm. Oregon highlights yielding (including at uncontrolled intersections) and special laws about pedestrians as core scoring items.

Nationally, pedestrian deaths reached 7,522 in 2022, the highest since 1981—underscoring why examiners focus hard on crosswalks and turning conflicts.

Passing a car stopped at a crosswalk is also listed as grounds for immediate failure on Oregon’s score sheet.

How to Avoid It

Slow earlier. At crosswalks, scan for people at the curb and yield fully—even if they haven’t stepped out yet.

At four‑way stops, remember: first to stop, first to go; if ties happen, yield to the right. On left turns, yield to oncoming traffic and people crossing.

Result When Corrected

Your turns and merges look smooth and deliberate; you avoid instant‑fail situations and win points for judgment and courtesy.

You also build habits that protect people on foot—exactly what examiners want to see. 

5. Lane Position and Lane Changes

The Problem

Drifting in your lane, hugging the curb, or changing lanes without checking over your shoulder are common point-losers.

Oregon’s drive-test score sheet specifically grades lane usage, lane position, observation, and lane changes (signaling and observation)—and lists dangerous lane/turn errors among grounds for immediate failure.

Why it matters beyond the test: U.S. research shows these errors are tied to serious crashes. In real-world data, when you monitor your blind spot, you are 14% less likely to crash and 23% less likely to have an injury. Additionally, using your lane-departure warning device will reduce single-vehicle sideswipes and head-on crashes.

Driver-assist alerts help, but you still need to look. Remember, your examiner will score manual mirror and shoulder checks, not technology.

How to Avoid It

Use visual anchors. Center the car between lane lines by referencing the lane stripe and your right and left side reference points. 

Before any lane change, check your mirrors, signal, and do a quick shoulder check, then move smoothly. Practice this routine with your instructor during your lessons until it feels automatic.

Result When Corrected

Your car tracks straight, your lane changes are predictable, and you’ll score higher on lane usage, position, and observation—all listed on Oregon’s scoring sheet.

6. Missing or Misreading Signs and Road Markings

The Problem

If you miss a school‑zone sign, a “No Turn on Red,” or a lane‑use arrow, you put yourself in jeopardy.

Oregon’s drive-test checklist explicitly states: “Do you know the meaning of signs, signals, and pavement markings?”

Not knowing—or noticing too late—leads to wrong‑lane turns, illegal moves, or last‑second swerves.

How to Avoid It

Study the Oregon Driver Manual and practice driving routes focused on reading the road ahead. Use a running scan: signs → signals → markings → people → vehicles.

Result When Corrected

You look prepared and composed, avoid deduction chains (wrong lane → sudden swerve → missed signal), and demonstrate knowledge the DMV specifically evaluates.

7. Backing, Parking, and Low‑Speed Control

The Problem

Many candidates lose points by backing too fast, staring at the camera instead of turning their head, or misjudging parking space angles.

Oregon tests backing and expects you to turn your head to see behind and beside you. Its score sheet also calls out parking/backing/re‑entry as graded skills.

How to Avoid It

Slow way down. Before reversing, look 360°, then back at a walking pace, glancing at your mirrors only briefly.

Practice straight‑line back‑ups and simple parking in low‑stress lots with cones. Build a repeatable routine with an instructor.

Result When Corrected

Your movements look precise and safe, you avoid curb bumps, and you gain points for vehicle control—an area that shores up your whole score.

8. Test‑Day Nerves and Poor Timing

The Problem

Anxiety can undercut performance on complex tasks like driving. In psychology, the Yerkes–Dodson law explains that when stress gets too high, performance drops.

U.S. data also show that stress correlates with worse outcomes on the road: an analysis of 30 years of NHTSA crash data found fatal crashes rise about 6% on U.S. Tax Day, a high-stress deadline.

Even Oregon DMV acknowledges nerves are normal
and emphasizes preparation: “You might be a little nervous… Most people are.” Their guidance is to study and practice, practice, practice before test day. 

How to Avoid It

  • Practice with purpose. Do a mock test with a certified instructor who uses real scoring language.
  • Know the logistics. Get plenty of rest, eat, and arrive early so you’re not rushed.
  • Use a routine. Two slow breaths before big maneuvers; name what you see (“crosswalk clear”) to anchor attention.
  • Schedule when ready. Oregon recommends planning ahead and arriving prepared; avoid cramming skills at the last minute.

Result When Corrected

You drive at your true skill level. Anxiety still exists—but it works for you, not against you. Your hands stay steady, you react on time, and your choices look calm and deliberate to the examiner. 

How a Lesson Might Help

Passing isn’t luck. It’s repeatable habits built with feedback. That’s why structured practice works so well:

  • Certified coaching: Our instructors are DMV/ODOT-certified and trained to teach how to drive safely; consequently, with the correct driving habits, your test score will be much higher.
  • Adult‑friendly and teen‑ready options: From online coursework to behind‑the‑wheel lessons, we meet you where you are and focus on calm, confident driving.
  • Test on site: When you’re ready, you can book your DMV road test at our Gresham or Beaverton locations—no extra running around. 

Are You Ready to Drive Forward?

You’ve just seen the mistakes that trip most people up on test day—and how to avoid each one.

  • Poor observation,
  • lack of situational awareness,
  • rolling stops,
  • speed and right-of-way issues,
  • lane position,
  • missed signs,
  • shaky parking or backing,
  • showing up without your permit,
  • And unmanaged nerves are all predictable and preventable.

With a few simple habits, you can turn those trouble spots into strengths and lift your score.

Fixing these isn’t only about passing a test. It’s about becoming a calmer, safer driver who protects themselves and everyone around them. When good habits feel natural, the drive feels easier, your choices become clear, and confidence replaces guesswork.

If you’re ready to take the next step, you can book your road test at our Gresham or Beaverton locations and take it in a familiar, low-stress setting.

If you’d like more guided practice first,  sign up for our teen or adult driver education course and learn with a DMV/ODOT-certified instructor who will teach you the skills needed for real-world safety.
