Most drivers will never encounter a wrong-way vehicle on a highway. If you do, you will have very little time, and whatever you do will come from instinct rather than deliberation.
That is exactly why it is worth reading this once now.
Move right, immediately
Wrong-way drivers disproportionately travel in what is, from their perspective, the right-hand lane — which is the fast lane for traffic going the correct direction.
If you see headlights approaching head-on, move to the right. Then keep moving right if you can. The rightmost lane and the shoulder are statistically the safest places to be.
This is the single most useful thing to know, and it is counterintuitive under stress, because the instinct in a head-on situation is to swerve whichever direction feels open. Deciding now that the answer is right makes it likelier to be what you actually do.
Slow down, get off the road
Reduce speed. Every mile per hour you remove is energy that will not be in a collision, and closing speed is what makes this crash type so lethal.
If you can safely reach the shoulder and stop, do it. Once stopped, keep your headlights on and stay in your vehicle with your seatbelt fastened. Do not stand outside on the shoulder of a highway.
Do not flash, honk, or try to intervene
The instinct to warn the other driver is a good one and it does not work here.
A wrong-way driver is frequently impaired, disoriented, or both. Flashing high beams at an impaired driver can worsen the situation — some drivers steer toward lights they are focusing on. Your priority is separation, not communication.
Leave the warning to the systems built for it.
Call 911 when you are safe
Once you are out of danger, call. Dispatchers act on wrong-way reports immediately and treat them as high priority.
Try to give:
- The road and direction of travel — including which direction the wrong-way vehicle is heading
- The nearest exit, milepost, or cross street you passed
- Vehicle description if you got one — color and type is plenty
- Whether it appeared to still be traveling
Do not worry about being the first to call. Multiple reports help dispatchers confirm location and direction, which is genuinely useful.
In Arizona, wrong-way detection systems on some corridors alert the Department of Public Safety automatically, which produces a faster response than 911 calls alone. But that coverage is not everywhere, and your call may be the only report on most of the road network.
If you realize you are the wrong-way driver
It happens, and it is usually a navigational error rather than anything reckless. What you do in the next few seconds matters enormously.
Do not attempt a U-turn on the freeway. Turning across lanes into oncoming traffic creates a broadside hazard at highway speed.
Pull to the right shoulder immediately — which, from your reversed perspective, is the left edge as you see it. That places you against the outside edge of the road rather than in traffic lanes.
Stop, turn on hazard lights, keep headlights on, stay belted in the vehicle, and call 911. Let law enforcement manage traffic and get you turned around safely.
If you are still on an off-ramp and have not reached the freeway, stop and back down the ramp only if it is completely clear and you can do so slowly. Most drivers who catch the error at the ramp resolve it safely — that is where a large share of wrong-way entries are caught, and it is the best possible place to catch one.
Reducing your own risk
- Wrong-way crashes concentrate at night and around dawn and dusk. Extra attention during those hours is well-placed.
- Unfamiliarity is a risk factor. On roads you do not know, slow down at interchanges and read signage rather than following the car ahead.
- Never drive impaired, and take the keys from someone who is about to. Impairment is the most consistent factor in these crashes, and this intervention prevents the whole chain rather than mitigating it.
One thing worth doing today
Tell someone else the "move right" rule. It takes ten seconds, most drivers do not know it, and it is the kind of thing that only helps if it is already in your head before you need it.
That is most of what awareness work is: a small number of specific, actionable facts, repeated until they are common knowledge.
