Independence Day

Independence Day Holiday Period Estimate for 2019

The National Safety Council estimates 565 people may die on U.S. roads this Independence Day holiday period. Holidays traditionally are a time of travel for families across the United States. Many choose car travel, which has the highest fatality rate of any major form of transportation based on fatalities per passenger mile. Holidays also are often a cause for celebrations involving alcohol consumption, a major contributing factor to motor vehicle crashes.

Independence Day is observed on July 4. The Independence Day holiday period varies from 1.25 to 4.25 days in length, depending on which day of the week the holiday falls. In 2019, the holiday falls on a Thursday, so the Independence Day holiday period is 4.25 days and extends from 6 p.m. Wednesday, July 3, to 11:59 p.m. Sunday, July 7.

National Safety Council estimate

There is uncertainty associated with any estimate. The 90% confidence interval for the estimate of traffic deaths this holiday is 500 to 637. This chart shows NSC Independence Day holiday fatality estimates and confidence intervals compared to the actual number of deaths. Because the holiday varies from 1.25 to 4.25 days long, the number of fatalities during the holiday also fluctuates widely from year to year.

A medically consulted injury is an injury serious enough that a medical professional was consulted. Based on the current medically consulted injury-to-death ratio of 114:1 and rounded to the nearest hundred, the estimate of nonfatal medically consulted injuries that will result from crashes during the holiday period is 64,500, with a 90% confidence interval of 57,000 to 72,700.

Lives saved with seat belts

Studies show seat belts, when used, are 45% effective in preventing fatalities among front-seat passenger car occupants (see note below for more detail). Based on the projected number of vehicle occupants who will wear safety belts, an estimated 224 lives may be saved this Independence Day holiday period. An additional 131 lives could be saved if all vehicle occupants wear safety belts.

Impaired Driving

Nationwide, alcohol-impaired fatalities (involving blood-alcohol content of 0.08 g/dL or higher) in 2017 represented 29% of the total traffic fatalities. During the Independence Day period, 39% of fatalities involved an alcohol-impaired driver, the highest percentage among all the major holidays. This chart shows the historic trend of the percent of fatalities involving an alcohol-impaired driver.

Note: Highest blood-alcohol concentration among drivers or motorcycle riders involved in the crash was 0.08 grams per deciliter (g/dL) or higher. The holiday periods used to calculate the percentages conform to the NHTSA holiday period definitions that add another quarter day to the periods used for the NSC estimate.

Although the reduction in the risk of fatal injury from wearing seat belts is higher for light-truck occupants at 50%, the lower figure for passenger car occupants is used in the calculations here as the more conservative measure. The most recent data from FARS indicate that seat belt use by fatally injured passenger car and light truck occupants was 48.4%.
