7 Parking Mistakes That Fail a DMV Road Test

US guide · 10 min read

Parking is where a road test stops being about knowing the rules and starts being about controlling the car. Most of the points lost here are not lost to bad steering — they are lost to speed, to a missed shoulder check, and to finishing a foot too far from the curb.

There is no national road test. Each state's DMV (or BMV, MVA, RMV, DPS) writes its own scoring sheet and its own list of automatic failures, and not every state even requires parallel parking. The mistakes below cost you on every scoring sheet — but for the exact tolerances and the number of correction attempts you're allowed, read your own state's driver handbook and scoring sheet before test day.

How the scoring actually works

Nearly every state test combines two separate mechanisms, and they fail you in different ways:

  • Point deductions. Small errors take points off a running total — stopping too far from the curb, a jerky stop, a late signal, taking an extra pull-up to straighten out. You fail when the total crosses your state's threshold, so these are survivable individually and fatal in bulk.
  • Automatic failure (a "critical error" or "dangerous action"). One is enough to end the test regardless of your score: a collision, striking the curb hard enough to mount it, disobeying a traffic control, or any moment where the examiner has to speak up or grab the wheel to keep you safe.

The practical implication: slow is free. Almost nothing on the deduction list gets worse when you take longer, and almost everything on the automatic-failure list gets more likely when you rush.

The seven that cost the most

1. Hitting or riding up on the curb

Cost: points for a light touch; automatic failure in most states if a wheel actually mounts the curb.

Why it happens: turning too late, then carrying too much speed while the wheel is still at full lock. At a crawl you can feel the tire kiss the curb and stop; at three miles an hour you're already on top of it.

The fix: reverse at a speed where you could stop within an inch. In an automatic that means covering the brake and letting the car idle back — no gas at all. If your mirror shows the rear tire closing on the curb, stop before contact, shift to Drive, steer away from the curb, pull forward two feet, and go again. A correction costs a couple of points. Mounting the curb ends the test.

2. Backing up on the camera alone

Cost: points on every sheet; automatic failure if you back into something you would have seen.

Why it happens: every new car sold in the US has had a backup camera since 2018, so most new drivers learned to reverse by watching a screen. The camera has blind spots at both rear corners — exactly where a cyclist or a child arrives from.

The fix: examiners want to see your head move. Before the car rolls back an inch: left mirror, right mirror, then turn and look out the rear window over your right shoulder. Use the camera as a supplement while you reverse, not as the reason you didn't look. Re-check over your shoulder every few feet — the space behind you is not the same space it was ten seconds ago.

3. Letting the car roll on a slope

Cost: points for a small roll; automatic failure if it rolls into something.

Why it happens: lifting off the brake on a hill before the accelerator has picked the car up, or shifting between Drive and Reverse without being fully stopped.

The fix: come to a complete stop before every direction change, keep your foot on the brake through the shift, and move your foot straight from brake to gas. On any noticeable grade, use the parking brake and release it once the car is already pulling.

4. Signal misuse around the maneuver

Cost: points, and more if traffic was present.

Why it happens: forgetting to signal before pulling alongside the space, or leaving the signal blinking through the whole reverse so the driver behind thinks you're about to pull out.

The fix: signal as you pull up level with the car in front. Cancel it once you're stopped and ready to reverse. Signal again — and check your mirror and blind spot again — before you pull back out into the lane.

5. Too many corrections

Cost: points per additional attempt on most sheets; a fail if you leave the space entirely or run out of attempts.

Why it happens: panicking at a slightly crooked car and starting a back-and-forth shuffle that walks the car further out of position with each pass.

The fix: most examiners expect one clean pull-up to straighten out, and some sheets cap the number of attempts — check yours. When it goes wrong, stop and diagnose instead of shuffling: if you're too far from the curb, pull forward while steering toward the curb and reverse again; if you're at too steep an angle, you started your turn too late and need to begin the whole maneuver further forward.

6. Swinging the nose into oncoming traffic

Cost: automatic failure if a car has to react.

Why it happens: the front of the car sweeps a long way out as the rear comes in — a fact most learners discover halfway through their first parallel park.

The fix: before the nose starts to arc out, look forward and check the oncoming lane. If anything is coming, stop and let it pass. Waiting is never a deduction.

7. Finishing out of position

Cost: points, scaling with how far off you are; a fail in some states if you end up over a line or blocking a lane.

Why it happens: stopping early out of fear of the curb, or never checking the final position at all.

The fix: for parallel parking, most states want the car parallel to the curb and within 12–18 inches of it — about a hand's width past the width of your own tire. For a bay, all four tires inside the painted lines with the car reasonably centered. And check what you're blocking before you call it done: driveways, crosswalks, and fire hydrants all have setbacks, and the distances vary by state.

Before you pull back out: SMOG

Most of the points lost around parking are lost leaving the space, not entering it. The standard driver's-ed sequence covers it:

S — Signal

On before you move, not as you move.

M — Mirrors

Rearview, then the side mirror on the traffic side.

O — Over the shoulder

An actual head turn into the blind spot. This is the one examiners watch for.

G — Go

Smoothly, and only into a gap you have actually seen.

Practice in the 3D Simulator

Work on the part a simulator can actually teach — where to start the turn, when to go to full lock, and where the car ends up — so your behind-the-wheel hours go on observation and traffic.
