For the first time in a long time, a calendar week went by in Denver without a single traffic death, according to the Denver Police Department.

The week between June 25 and July 1 wasn’t without carnage, however. Motorists inflicted life-changing injuries on three people walking. Four people traveling in cars were injured, and so was one motorcyclist.

Denver PD responded to 419 crashes in the past seven days and arrested 33 people for driving drunk or high.

With this series, we aim to remind politicians, transportation officials, local media, and the public that the cost of inaction on traffic safety policies is extremely high. The longer it takes to redesign our car-centric streets, the more people will get hurt or killed.

The Hancock administration and Denver PD still lack a protocol for alerting the public to serious traffic collisions and tallying them accurately, despite the mayor’s ostensible commitment ending traffic deaths, announced more than two years ago. Hopefully documenting this information, gathered from Denver PD reports, will help drive change from decision-makers and elevate the profile of this public health crisis.
