Driving home after a night shift: how to get there awake
Why the drive home after a night shift is so risky and how to stay safe
Nurses, factory workers, police officers, truckers, hotel staff and many others finish work as the sun comes up. Then they get behind the wheel. Their bodies are telling them to sleep, and the morning light can make them feel more awake than they are.
Researchers have measured how dangerous this drive is. In a study at a closed test track, 16 night shift workers drove for two hours twice: once after a night shift and once after a normal night’s sleep. After the night shift, 6 of the 16 drives included near crashes, and 7 were stopped early for safety. After sleep, there were none [1].
Why the drive home is so dangerous
Your body clock. Humans are built to sleep at night. The strongest pull toward sleep comes in the early morning hours. Working through it builds a big sleep debt.
Long time awake. Many night workers have been awake for 18 hours or more by the end of a shift. Research has compared this to drinking. After about 17 hours awake, performance drops to about the level of a 0.05 blood alcohol concentration. After 24 hours, it matches about 0.10, above the legal limit in every state [2].
Microsleeps. A tired brain can shut off for a few seconds without warning. At 55 mph, a car travels more than 80 feet per second.
The familiar route. A drive you know well invites your mind to drift.
The same pattern shows up in hospitals. A national study looked at first year doctors after extended shifts of 24 hours or more. Their odds of a reported crash were 2.3 times higher, and near misses were 5.9 times higher [3].
Warning signs you are too tired to drive
- Yawning again and again, or heavy eyelids
- Trouble keeping your head up
- Drifting out of your lane or hitting rumble strips
- Missing your exit or a turn
- Not remembering the last few miles
- Tailgating or missing traffic signs
If you notice any of these, get off the road at the first safe place. Federal safety officials list these same signs [4].
Before you leave work
Take a short nap. A nap of about 15 to 20 minutes before driving can boost alertness. Some workers nap in a break room or in their parked car before leaving.
Try caffeine and a nap together. Drink a cup of coffee, then nap for 15 to 20 minutes. The caffeine kicks in around the time you wake up. Caffeine alone only buys a short time and does not replace sleep.
Check yourself honestly. If you nodded off at work or feel foggy, do not drive.
Other ways to get home
- Carpool with a coworker, and trade off driving or let the most alert person drive
- Use public transit if a route works with your schedule
- Take a ride share or taxi after very long or hard shifts
- Ask a family member to pick you up after a run of night shifts
- Sleep near work if your employer offers a rest space, then drive home rested
If you must drive
- Keep the trip as short as possible
- Avoid errands on the way home
- Keep the car cool, but do not rely on cold air or loud music to stay awake
- Pull over to a safe spot and sleep if warning signs appear
- Never use cruise control when you are tired
Warning: Opening the window, turning up the radio or chewing gum do not stop sleep. If you are fighting to stay awake, pull over to a safe place and sleep, even for 20 minutes.
What employers can do
Shift work is part of many essential jobs. Employers can lower the risk:
- Provide quiet rest areas for naps before workers drive home
- Offer ride programs or transit passes after long or overnight shifts
- Limit back to back night shifts and extended shifts when possible
- Avoid overtime that runs into the commute without a rest break
- Teach staff about drowsy driving and make it acceptable to say “I’m too tired to drive”
Better sleep makes safer drives
- Sleep in a dark, cool, quiet room. Use blackout shades and earplugs.
- Wear sunglasses on the way home to reduce morning light, if it is safe to see well.
- Keep a regular sleep schedule on workdays when you can.
- Talk with a doctor if you snore loudly or still feel exhausted after sleep. You could have a sleep disorder such as sleep apnea.
Checklist: getting home safe after a night shift
Checklist from Safety Behind the Wheel Foundation
- I know the warning signs of drowsy driving
- I plan a short nap before driving after hard shifts
- I have a backup ride option saved in my phone
- I go straight home, with no extra errands
- I will pull over and sleep if I start to nod off
- I talked with my doctor if I am tired all the time
Frequently asked questions
Is coffee enough to get me home?
Coffee helps for a short time. It does not erase sleep debt, and you can still have microsleeps. Pair it with a short nap, or get a ride.
Can I be charged with a crime for falling asleep at the wheel?
Yes, in some cases. Drivers who cause serious crashes while too tired can face charges such as reckless driving or vehicular homicide, depending on state law. See our article on drowsy driving laws.
Do driver alert systems in cars help?
Some newer cars watch your eyes or steering and sound an alert. They can help, but they cannot keep you awake. When the alert sounds, pull over.
