This thread covers page 560 of your 2024+ Toyota Tacoma (4th Gen) Owner's Manual, focusing on emergency flasher operation, when to use them, and important state laws.
What this guide covers:
Activating Emergency Flashers:
To activate your emergency flashers, press the hazard light switch located on the dashboard. All turn signal lights will begin flashing simultaneously. Press the switch again to deactivate.
Emergency flashers serve as a warning signal to other motorists when your vehicle must stop on the roadway due to mechanical problems or other emergencies.
When to Use Emergency Flashers:
4th Gen Tacoma Safety Feature:
Your Tacoma includes automatic flasher activation when airbags deploy or during severe rear-end collisions. Once activated, the system runs for approximately 20 minutes before automatically shutting off to preserve battery power. If you need to disable them sooner, press the hazard switch twice.
Note that automatic activation depends on impact severity and collision type - not all accidents will trigger this feature.
This automatic activation ensures your vehicle is visible even if you're unable to manually activate the flashers after a collision. The 20-minute auto-shutoff preserves battery power while giving adequate time for emergency response.
NOTICE: If the emergency flashers are used for a long time while the engine is not running, the battery may discharge.
The 4th Gen Tacoma's push-button start system may experience battery drain when accessories remain powered with the engine off. If you need extended flasher use (over 30 minutes), consider periodically starting the engine for 15-20 minutes to allow the alternator to recharge the battery, but only if safe to do so and not in an enclosed space.
Maximize Visibility:
Do NOT Use Flashers While Driving in Poor Weather
With hazards on and rain/snow already blurring visibility, other drivers may not be able to tell which lane you're in or if you're changing lanes. Turn on headlights and taillights instead.
IMPORTANT: This is ILLEGAL in many states including Alaska, California, Hawaii, Illinois, Louisiana, Massachusetts, Nebraska, New Mexico, Rhode Island, Florida, and Kansas. Check your local laws as restrictions vary by state.
Do NOT Use Flashers to Signal Turns or Lane Changes
Hazard lights obscure your intended direction. Other drivers see ALL lights flashing and can't tell where you're going. This defeats the purpose of turn signals.
Do NOT Think Flashers Make Illegal Parking Legal
Turning on emergency flashers does not make an unsafe or illegal stop safe or legal. Don't use flashers as permission to park in no-parking zones.
Do NOT Leave Flashers On Unnecessarily Long with Engine Off
Excessive flasher use drains the battery (as Toyota manual warns). Turn off flashers once help arrives or you've secured the vehicle.
State Laws Vary Significantly:
Many states prohibit or restrict driving with hazard lights activated in certain conditions. States with complete or partial prohibitions include Alaska, California, Hawaii, Illinois, Louisiana, Massachusetts, Nebraska, New Mexico, Rhode Island, Florida, Kansas, and others.
Note on Funeral Processions: Most states permit hazard lights when part of a funeral procession, though specific requirements vary by state. Check your local regulations.
Road safety experts generally advise against using hazard lights while driving because:
Q: How long can I run the emergency flashers with the engine off?
A: The manual warns that extended flasher use can discharge the battery. As a guideline, 15-30 minutes is generally safe on a healthy battery. Beyond that, consider starting the engine periodically (15-20 minutes) to recharge, but only if safe and not in an enclosed space.
Q: When should I use emergency flashers vs. regular signals?
A: Use regular turn signals when you're in control of the vehicle and making normal maneuvers (lane changes, turns, merging). Use emergency flashers only when you're experiencing an emergency that requires warning other drivers (breakdown, accident, must pull over immediately). Never use flashers while actively driving in normal conditions.
Q: Will my flashers work if the battery is dead?
A: No. Emergency flashers require battery power to operate. If your battery is completely dead, the flashers will not function. This is why the manual warns about extended flasher use draining the battery when the engine is not running.

Emergency Flasher Operation
Basic Operation (Page 560)
Activating Emergency Flashers:
To activate your emergency flashers, press the hazard light switch located on the dashboard. All turn signal lights will begin flashing simultaneously. Press the switch again to deactivate.
Emergency flashers serve as a warning signal to other motorists when your vehicle must stop on the roadway due to mechanical problems or other emergencies.
When to Use Emergency Flashers:
- Breakdown or mechanical failure (vehicle cannot maintain safe speed)
- Flat tire (while pulling to roadside and during tire change)
- Engine overheating (requires immediate stop)
- Accident involvement (after collision while awaiting assistance)
- Slow-moving hazard (when towing or driving significantly below traffic speed)
- Roadside emergency (any situation requiring stop in travel lane or shoulder)

Real-World Tips & Road Safety Best Practices
Emergency Flasher Best Practices
Maximize Visibility:
- Activate flashers BEFORE pulling over - Alerts following drivers you're slowing down and gives them time to change lanes
- Turn on headlights AND flashers at night - Flashers alone may not provide adequate rear visibility
- Use LED flares for added visibility - Provides extra protection beyond flashers, especially in low-visibility conditions
- Signal law enforcement acknowledgment - When being pulled over, activating flashers shows the officer you acknowledge their signal and are complying

Know Your State's Hazard Light Laws
State Laws Vary Significantly:
Many states prohibit or restrict driving with hazard lights activated in certain conditions. States with complete or partial prohibitions include Alaska, California, Hawaii, Illinois, Louisiana, Massachusetts, Nebraska, New Mexico, Rhode Island, Florida, Kansas, and others.
Note on Funeral Processions: Most states permit hazard lights when part of a funeral procession, though specific requirements vary by state. Check your local regulations.
Road safety experts generally advise against using hazard lights while driving because:
- Flashers obscure turn signals
- Other drivers may think you're stopped and move into opposing lanes
- Use headlights/taillights in poor weather instead
- Reserve flashers for true emergencies
