A traffic emergency is when two vehicles are about to collide. A vehicle emergency is when tires, brakes or other key parts fail. Safe habits prevent most emergencies, but when one happens, how well you act decides if you crash.
Turning is often faster than stopping
Stopping is not always the safest choice. When there is not enough room to stop, you may need to steer away from what is ahead. You can almost always turn to miss an obstacle faster than you can stop.
Warning: top-heavy vehicles and tractors with multiple trailers may flip over in a sharp turn.
Keep both hands on the wheel. To turn quickly you need a firm grip with both hands. The surest way to have both hands ready in an emergency is to keep them on the wheel all the time.
How to turn quickly and safely
- Do not brake while turning. It is very easy to lock the wheels in a turn, and then you may skid out of control.
- Do not turn more than needed to clear the object. The sharper you turn, the greater the chance of a skid or rollover.
- Be ready to counter-steer — turn the wheel back the other way once you pass the object. If you are not ready, you will not do it fast enough. Think of emergency steering and counter-steering as one single driving action.
Where to steer
- If an oncoming driver drifts into your lane, move to your right. When that driver notices, the natural reaction is to go back to their own lane.
- If something blocks your path, the best direction depends on the situation. If you have been checking your mirrors, you will know which lane is empty.
- If the shoulder is clear, going right may be best. Traffic rarely uses the shoulder, while a vehicle could be overtaking you on the left.
- If you are blocked on both sides, moving right may be best. At least you will not push anyone into oncoming traffic and a possible head-on crash.
Leaving the road
Sometimes driving off the road is less risky than hitting another vehicle. Most shoulders are strong enough to hold a large vehicle, so they are a possible escape route.
- Avoid braking until your speed drops to about 20 mph. Then brake very gently so you do not skid on the loose surface.
- Keep one set of wheels on the pavement if you can. This helps you keep control.
- Stay on the shoulder if it is clear until you come to a stop. Before you return to the road, signal and look in your mirrors.
Returning to the road before you stop
If you are forced back onto the road before you can stop:
- Grip the wheel firmly and turn sharply enough to get back onto the pavement in one safe move.
- Do not edge back gradually. Your tires might grab suddenly and you could lose control.
- When both front tires are on the pavement, counter-steer immediately. Make the two turns as one steer–counter-steer move.

Review questions with answers
- In an emergency, you can almost always ________ to miss an obstacle more quickly than you can stop.
- Turn
- Downshift
- Honk
- Use the parking brake
Show answer
TurnStopping is not always safest. You can usually steer around an object faster than you can stop.
- Which vehicles may roll over if steered sharply in an emergency?
- Empty straight trucks only
- Small buses only
- Cars
- Top-heavy vehicles and tractors with multiple trailers
Show answer
Top-heavy vehicles and tractors with multiple trailersTop-heavy vehicles and tractors pulling multiple trailers may flip over in a quick, sharp turn.
- During a quick emergency turn, you should:
- Brake hard while turning
- Not brake while turning
- Pump the brakes while turning
- Pull the parking brake
Show answer
Not brake while turningBraking while turning can easily lock the wheels and cause a skid. Brake before or after, not during, the turn.
- "Counter-steering" means:
- Turning on the four-way flashers
- Steering toward oncoming traffic
- Turning the wheel back the other way after you pass an obstacle
- Holding the wheel straight while braking
Show answer
Turning the wheel back the other way after you pass an obstacleAfter swerving past an object, you turn the wheel back the other way. Plan emergency steering and counter-steering as one action.
- An oncoming driver drifts into your lane. The best move usually is to steer:
- To your right
- To your left
- Straight ahead and brake hard
- Into the center line
Show answer
To your rightMove right. When the other driver notices, the natural reaction is to return to their own lane.
- If you are blocked on both sides, steering to the right may be best because:
- The right side has fewer potholes
- Trucks have better mirrors on the right
- Turning right is always faster
- You will not force anyone into oncoming traffic and a head-on crash
Show answer
You will not force anyone into oncoming traffic and a head-on crashMoving right at least avoids pushing another driver into the opposing lane.
- If you must leave the road in an emergency, you should avoid braking until your speed drops to about:
- 40 mph
- 20 mph
- 5 mph
- 50 mph
Show answer
20 mphAvoid braking until about 20 mph, then brake very gently to avoid skidding on the loose surface.
- When you drive onto the shoulder to escape a crash, it helps to:
- Put all wheels on the shoulder right away
- Brake hard at once
- Keep one set of wheels on the pavement if possible
- Turn off the engine
Show answer
Keep one set of wheels on the pavement if possibleKeeping one set of wheels on the pavement helps you maintain control.
- You swerved onto the shoulder to avoid a crash, but you must get back on the road before you can stop. You should:
- Hold the wheel tightly, turn sharply enough to get right back on, then counter-steer when both front tires are on the pavement
- Ease back onto the road very gradually
- Brake hard while turning back
- Turn as little as possible and let the tires climb the edge slowly
Show answer
Hold the wheel tightly, turn sharply enough to get right back on, then counter-steer when both front tires are on the pavementDo not edge back gradually; tires may grab and you can lose control. Turn sharply, then counter-steer at once when both front tires are on the pavement.
- Most road shoulders are too weak to support a large vehicle, so you should never use them to escape.
- True
- False
Show answer
FalseFalse. Most shoulders are strong enough to hold a large vehicle and are an available escape route.
- The best way to make sure both hands are on the wheel during an emergency is to:
- Practice grabbing it quickly
- Use a steering knob
- Keep both hands on it all the time
- Steer with your knees until needed
Show answer
Keep both hands on it all the timeKeep both hands on the wheel at all times so you are ready to turn quickly.
- When steering around an obstacle, how much should you turn?
- As sharply as possible
- Enough to reach the far shoulder
- Twice what seems needed
- No more than needed to clear the obstacle
Show answer
No more than needed to clear the obstacleThe sharper the turn, the greater the risk of a skid or rollover. Turn only as much as needed.
- If the shoulder is clear and something blocks your lane, going right may be best because:
- Traffic rarely uses the shoulder, while a vehicle may be overtaking you on the left
- The left lane is always slower
- Trucks may not use the left lane
- Right turns do not need counter-steering
Show answer
Traffic rarely uses the shoulder, while a vehicle may be overtaking you on the leftTraffic is unlikely on the shoulder, while a vehicle could be passing you on the left. Your mirrors tell you which way is open.
- A "traffic emergency" happens when:
- A tire blows out
- The brakes fail
- Two vehicles are about to collide
- The engine overheats
Show answer
Two vehicles are about to collideA traffic emergency is when two vehicles are about to crash into each other. A vehicle emergency is a failure of tires, brakes or other parts.
