How Daylight Saving Time Affects School Children and Safety

Why do children wait for buses in the dark after the clocks change?

The pattern is consistent across the country: elementary schools open between 8:00 and 9:00 a.m. Middle and high schools start earlier, typically between 7:30 and 8:30 a.m. The reasoning is logistical. Older students get the earliest buses, so the same fleet can then run elementary routes later.

In Washington, on the March equinox (20 March 2026), sunrise is at 7:13 a.m. A child at a bus stop at 7:00 a.m. is waiting in pre-dawn conditions. That is not an edge case. That is the normal start to the day for millions of students for weeks after the clocks change.

What happens to the morning commute when clocks spring forward?

When clocks spring forward on the second Sunday of March, the sun rises one hour later by the clock. On 8 March 2026, Washington moves from EST to EDT at 2:00 a.m. The child whose bus comes at 7:10 a.m. boards before first light.

This is not a one-day issue. For northern states, the stretch of dark starts lasts longer. In the weeks after the transition, children walk to school, wait at bus stops, and stand at crosswalks in pre-dawn gloom. The same applies after the fall back transition in November, when afternoons darken early, but the morning commute is the sharper danger.

The documented consequence: the Monday after spring forward sees a measurable increase in traffic accidents involving pedestrians. The hour of lost sleep compounds the hazard. Drivers are fatigued. Children are harder to see.

Did dark mornings kill year-round daylight saving time before?

The United States tried year-round DST once. In January 1974, during the energy crisis, Congress enacted it. The goal was fuel conservation. The result was a political disaster.

The trouble was not the evenings. The trouble was the start of the day. Children walked to school in near-blackness for months. Parents organized protests. The backlash was swift and bipartisan.

By August 1974, the experiment was abandoned. The country switched back to standard time for the winter months. The lesson was clear: the safety of children waiting for school buses in the dark is a more powerful political force than energy savings.

Today, that historical failure is the primary argument against legislation to make DST year-round. Every proposal must answer the question: what do we do about the children?

Is permanent daylight saving time a safety risk for schoolchildren?

The Sunshine Protection Act, which would make DST permanent nationwide, passed the Senate in 2022 but stalled in the House. It has been reintroduced in subsequent sessions. As of 2026, no bill has become law.

The core objection is the winter morning. Under year-round DST, sunrise in Washington on the December solstice (21 December 2026) would shift one hour later than the standard-time sunrise of 7:22 a.m. That is an hour of additional pre-sunrise conditions for the morning commute. For northern states, the sunrise delay pushes first light deep into the morning rush.

Supporters of permanent DST argue that the evening gain is worth it: more daylight after school for sports, activities, and family time. Opponents point to the 1973-74 experiment and ask why we would repeat a known failure. Neither side can cite perfect data, but the safety concern for children is the argument that has blocked every attempt at making DST year-round since 1974.

What does the research say about sleep and academic performance?

The Monday after spring forward is not just darker. It is also a day when students have lost an hour of sleep. Research has documented an increase in traffic accidents on that Monday, particularly for teen drivers. The combination of sleep deprivation and reduced visibility creates a measurable risk.

Academic performance also takes a short-term hit. Studies have found lower test scores and increased classroom distraction in the week following the spring transition. The effect is small but consistent. For middle and high school students, who already start school earlier than elementary students, the loss of sleep compounds an existing difficulty: many teenagers are biologically predisposed to later sleep schedules.

How does latitude change the dark morning problem?

The dark morning problem is not uniform across the United States. Latitude matters.

In Washington (38.9° N), sunrise on the December solstice under standard time is 7:22 a.m. The further north you go, the later the sun rises in winter, and the more severe the impact of shifting that sunrise one hour later.

This is why northern states are disproportionately affected by DST policy. A year-round DST that is tolerable for Florida is unworkable for Minnesota. The 1973-74 experiment failed in part because the dark mornings were concentrated in the population centers of the Northeast and Midwest, where schoolchildren were sent into darkness for months.

States that have opted out of DST entirely (Arizona and Hawaii) do not face this difficulty. Arizona stays on Mountain Standard Time year-round. Hawaii stays on Hawaii-Aleutian Standard Time. Neither state asks children to stand at bus stops in the dark for an extra hour in winter.
