Between April 28 and May 4, one person walking and three people driving were seriously injured in traffic collisions on Denver streets. One person on a motorcycle was killed.

Other things you should know: Denver PD did not arrest a single person for driving either drunk or high on Wednesday, May 2. Four months into 2018, police resources have been used to respond to more than 8,000 crashes.

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, despite the mayor’s ostensible commitment ending traffic deaths, announced two years ago. Hopefully documenting this information will help drive change from decision-makers and elevate the profile of this public health crisis.
