Daylight savings time begins on November 2nd, and history shows a troubling pattern—traffic accidents increase by an average of 6% during the twilight hours on this day each year. One of the biggest factors behind this spike is driver fatigue. In fact, the National Transportation Safety Board (NTSB) estimates that fatigue plays a role in 30–40% of all heavy truck accidents.
Why Daylight Savings Time Poses Driving Risks
1. Sleep Disruption
Even a one-hour time change can disrupt your sleep cycle, slowing reaction times and impairing decision-making—both of which make drivers more vulnerable to mistakes.
2. Circadian Rhythm Changes
Your body’s internal clock relies on consistent light and darkness cues. Shifting the clock can throw off your rhythm, causing drowsiness and decreased alertness.
3. Light-to-Dark Transitions
The change moves daylight from morning to evening, making early commutes darker and potentially reducing visibility—especially in the first few days after the switch.
4. Pedestrian Safety Concerns
Darker mornings mean pedestrians are harder to see, increasing the risk of pedestrian-involved accidents near schools, bus stops, and intersections.
How Drivers Can Reduce the Risk
-
Adjust Your Sleep Gradually
In the days before the time change, try going to bed and waking up 15 minutes earlier each day. This gradual shift helps your body adapt. -
Stay Alert for Pedestrians
Pay extra attention near crosswalks and school zones. Pedestrians can help by wearing reflective or bright clothing. -
Check Your Vehicle Lighting & Visibility
Ensure headlights, taillights, and brake lights are working. Clean your windshield, replace worn wipers, and verify that your defroster works properly. -
Plan Trips Around Daylight
If possible, schedule driving during daylight hours to reduce fatigue and improve visibility. Have safe stopping points planned in advance.
The November 2nd time change might seem small, but even a one-hour shift can have a major effect on driver alertness and road safety. Preparing ahead can help you stay sharp, stay visible, and stay safe.
