10 Road Signs You Need to Know Before Taking the Permit Test

10 Road Signs Every New Driver Must Know (And What They Really Mean)
Know the Signs, Drive with Confidence
Preparing for your road test or just starting behind-the-wheel lessons?


Then you already know that traffic signs aren’t just a minor part of driving they’re essential. Road signs tell us how to behave on the road and help keep everyone safe. 

Missing or misunderstanding them during your test (or in real life) can lead to serious consequences, from point deductions to dangerous collisions.
In this guide, we’re covering 10 of the most important road signs every permit-holding student driver needs to know. We’ll go beyond the definitions to give you clear examples, test tips, and smart ways to remember each one.

If you're studying for your permit test, about to begin on-road driving lessons, or reviewing with a parent or driving coach, this is the perfect place to start.


1. Stop Sign – More Than Just a Pause

Most people know what a stop sign means. But during your road test, it's not just about stopping—it's about how and where you stop.

What It Looks Like: Red octagon with white letters

What to Do:

  • Come to a complete stop at the white line or before entering the crosswalk.
  • Count to three seconds.
  • Check left, right, then left again.
  • Common Mistake: Rolling stops (also called California stops) will cost you points. Always come to a hard stop, even if no one is around.

Test Tip: If visibility is blocked, stop first, then creep forward slowly for a better view before continuing.



2. Yield Sign – Know When to Wait

Yield signs are often misunderstood. They don’t mean stop, but they also don’t mean go.
What It Looks Like: Red and white upside-down triangle

What to Do:
  •  Slow down and be prepared to give the right of way.
  •  Let vehicles or pedestrians who are already in motion go first.
Where You'll See It: At roundabouts, highway on-ramps, side streets joining busier roads.
Real-World Reminder: Imagine you're entering a roundabout, and a car is already circling. If you don't yield, you could cause a crash.

Memory Trick: Yield = "You go ahead, I'll wait."


3.  Do Not Enter – One-Way Mistake Prevention

Ignoring this sign can send you into oncoming traffic.

What It Looks Like: Red circle with a white rectangle in the middle

Where You'll See It: Start of one-way streets, freeway off-ramps, construction zones

What to Do:
  • Never go past this sign. If you accidentally do, pull over safely and turn around as soon as possible.

Test Tip: Seeing this sign and avoiding it is part of situational awareness. Your examiner will notice.


4.  No U-Turn – Don’t Flip the Script

Just because a road looks clear doesn’t mean it’s legal to turn around.

What It Looks Like: Black U-turn arrow with a red slash through it

What to Do:

  • Don’t make a U-turn here.
  • Find a designated turnaround point or intersection where U-turns are permitted.

Test Tip: Making a U-turn where this sign is posted can be an automatic fail. Always check for signage before making directional changes.


5. School Zone – Always Slow Down

Speeding through a school zone is one of the most serious infractions you can make.

What It Looks Like: Yellow pentagon with two figures walking

What to Do:

  • Reduce speed to the posted limit (often 20 mph or less)
  • Stay alert for crossing guards, buses, and children on sidewalks

When It Applies: During posted school hours, and sometimes even outside of them. When in doubt, slow down.

Test Tip: Speeding in a school zone is often considered a non-negotiable fail on most state exams.

6. Traffic Signal Ahead – Don’t Get Caught Off Guard

This warning gives you time to prepare before reaching a traffic light that may not be easily visible.

What It Looks Like: Yellow diamond with a traffic signal icon

What to Do:

  • Ease off the gas
  • Prepare to stop if the light is red or turning yellow

Real-World Scenario: You're going around a curve and suddenly see brake lights. If you'd seen the sign, you would have been ready. Now you’re slamming your brakes.

Pro Tip: Always scan far ahead so you don’t miss these signs.



7.  Deer Crossing – It's No Joke

Deer strikes cause thousands of vehicle accidents a year. These signs are for real.

What It Looks Like: Yellow diamond with a leaping deer silhouette

Where You'll See It: Rural roads, wooded areas, highways near open fields

What to Do:

  • Slow down
  • Stay alert, especially at dawn or dusk

Test Tip: In areas with deer signs, your examiner may test how alert and cautious you are.

Memory Trick: See a deer sign? Ease up and scan the road edges.



8. Steep Hill / Grade – Control Your Descent

This sign warns you about a steep downgrade ahead.

What It Looks Like: Yellow diamond with a truck heading downhill

What to Do:

  • Shift to a lower gear if using a manual transmission
  • Use engine braking rather than panic braking

Why It Matters: Braking hard on a steep hill can cause your tires to skid, especially in wet conditions. This is also a major cause of overheating brakes in trucks.

Test Tip: You may be asked how to respond to this sign during your written exam.


9.   Merge Sign – Share the Road Smoothly

Merging is about timing, space, and awareness.

What It Looks Like: Yellow diamond with an arrow merging from the side

What to Do:

  • Signal early 
  • Check mirrors and blind spots
  • Adjust your speed to merge smoothly

Common Mistake: Speeding up aggressively to cut someone off or braking suddenly at the merge point.

Pro Tip: Show your instructor that you can adapt, anticipate, and communicate with other drivers.



10. Slippery When Wet – Weather Warning

This sign is a heads-up to reduce speed and increase caution.

What It Looks Like: Yellow diamond with a car and wavy skid marks

When It Applies: Rain, ice, oil patches, wet leaves

What to Do:

  •  Slow down before curves
  • Avoid sudden acceleration or braking

Memory Trick: Wavy lines = wobbly car. Stay smooth and steady.
