Don't Veer for Deer: Lights, Aim, and Smart Dusk Driving

Written by Ken Colavito

AutoSkillsRule Monthly Tech Article · November 2026 · Daylight Saving Time Ends & Peak Deer Season

The clocks fell back this weekend, and your drive home just moved into the dark. That's the exact window when deer are on the move. Dawn and dusk are their busiest hours, so your commute now lands right on top of them.

November is the peak of the rut, which is deer mating season. Bucks chase does and stop paying attention to roads. New Jersey wildlife officials put the peak from late October through November and into mid-December. AAA Northeast counted 5,271 deer crashes in NJ from October to December 2018. That's one every 25 minutes, and 77 percent happened outside daylight hours. The good news: a little shop prep and a few smart habits stack the odds in your favor.

1. Know the danger zones and the clock

Why: Deer move most in the early morning and dusk, which are the hours you can see worst.

  • Wooded stretches, field edges, creek crossings and deer-crossing signs are the hot spots. Suburbs count too. In that same 2018 stretch, AAA counted 396 deer crashes in Middlesex County. Deer don't read zoning maps.

  • See one deer? Expect more. They often cross in single file.

  • Scan the road edges, not just your lane. Look for the shine of eyes.

2. Give your headlights a checkup

Why: Dim bulbs and hazy lenses shrink how far ahead you can see, and a deer needs only a second to cross that distance.

  • Park facing a wall or garage door at night. Compare left and right. One dim side point to a bulb or connection. Both dim points to old bulbs or foggy lenses.

  • Replace halogen bulbs in pairs. They fade slowly, so you don't notice until the new one makes the old one look sad.

  • Don't touch new halogen glass with bare fingers. Skin oil makes hot spots that shorten bulb life. Use clean gloves or a clean rag.

  • Yellow or foggy lens? Sunlight (UV) breaks down the clear plastic over the years. Restoration kits work, but only if you finish with a UV-protective clear coat. Skip that step and the haze comes back fast.

  • Match the bulb type to the housing. "Plug-in" LED bulbs in a halogen housing can scatter light and blind oncoming drivers. Stick with what the housing was designed for.

  • Clean the glass inside and out. A greasy inside windshield turns oncoming headlights into starbursts.

  • Check low beams, high beams, brake lights and turn signals while you're at it.

3. Check your aim with the wall test

Why: Lights aimed too low waste your light. Lights aimed too high blind everyone else. Either way, you see less.

A quick note on where to look things up. Your owner's manual covers things like bulb types and fuse locations. The actual headlight aim spec and procedure usually live in the factory service manual, which a shop will have. The wall test below is a rough check to see whether your lights are way off. It is not a replacement for the factory procedure.

  1. Park on level ground, square to a flat wall or garage door, and back up until the front of the headlights is about 25 feet from the wall. Keep the ground level the whole way. A slope throws the numbers off.

  2. Set tire pressures to the door-jamb sticker and remove any heavy cargo.

  3. Measure the height from the ground to the center of each headlight. Mark each height on the wall with tape, then add a horizontal line of tape across both marks.

  4. Turn on the low beams. The top of the brightest part of each beam should sit at or slightly below the horizontal tape line, and both sides ought to match.

  5. Off by a lot? Don't force the adjusters. Check your vehicle's service information for the procedure, because some newer vehicles use aiming equipment or a scan tool. Or have a shop aim them to the factory spec.

For a step-by-step reference you can follow along with, see the Utah Department of Public Safety headlamp aiming chart linked in the sources below.

4. Drive like it's deer o'clock

Why: Your lights only reach so far. Speed decides whether you can stop inside that distance.

At 55 mph, stopping takes roughly 250 to 300 feet on dry pavement. That's a rule of thumb, including about a second and a half to react. Many low beams don't light up that far. So slow down where it's wooded, especially at dusk and dawn.

  • Use high beams when nobody is coming. They help you spot eyes and movement sooner.

  • Don't tailgate. The driver ahead could have to stop hard for a deer, and you'll need room.

  • Seat belt on, every trip. It's the single best thing you can do for a bad day.

  • Don't count on gadgets. AAA says flashing your high beams or honking won't keep deer off the road.

  • Local police in nearby South Brunswick have noted that the time change aligns your commute with peak deer activity. Consider this your reminder.

5. Deer in your lane: brake, don't swerve

Why: Swerving trades a deer for a head-on crash or a tree. Those are usually worse.

  • Brake firmly and hold the wheel with both hands.

  • Stay in your lane.

  • Don't speed up. It makes things worse.

  • Deer standing in the road? Wait for it to cross and for the road to clear. Don't try to drive around it.

6. After a hit: the 10-minute inspection

Why: A car can look fine and still be leaking coolant or hanging a part by a thread.

  1. Pull off the road if you can. Turn on the hazard lights.

  2. Call 911 if anyone is hurt or the road is blocked. In NJ, report any deer collision to local police.

  3. Stay away from the animal. Hooves and antlers can still hurt you even if it's down.

  4. Take photos of the destruction and the scene.

  5. Walk around the car using the list below.

  • Steam, puddle under the car, or rising temp gauge: could be a cracked radiator, hose or condenser. Don't drive. Overheating ruins engines fast. Tow it.

  • Hood won't latch or is bent: latch or structure damage, and the hood could fly open. Don't drive. Tow it.

  • Cracked headlight or hanging bumper cover: secure the part and check lights. Drive only if lights work and nothing is dragging or loose. Otherwise tow.

  • Bulging, flat or damaged tire, or car pulls to one side: tire or suspension damage. Don't drive. Tow it.

  • Warning lights, burning smell or odd noises: hidden damage. Tow it.

  • Hybrid or EV with a visible orange cable, cracked battery case, smoke or hissing: high-voltage damage. Stay away and call 911.

When in doubt, tow. A tow costs less than an engine.

One more thing for your insurance file: in NJ, deer damage is covered by comprehensive coverage. If you only carry liability, it generally isn't. Check your policy before you need it.

Quick checklist

  • Both headlights equally bright

  • Bulbs replaced in pairs when needed

  • Lenses clear, or restored and sealed with UV clear coat

  • Windshield clean inside and out

  • Wall test done; if aim looks off, shop aims to factory spec from service information

  • Slow down at dusk and dawn in wooded areas

  • High beams on when no one is coming

  • Seat belt on, every trip

  • Know the rule: brake, don't swerve

  • After any hit: hazards on, photos, police, walk-around, tow if in doubt

  • Insurance policy checked for comprehensive coverage
