This dataset provides statistics from EPS's Curb the Danger program. EPS's Curb the Danger program has been available since 2006, where the public can call 911 when they spot someone they suspect is driving impaired, and if possible report the last direction of travel of the suspect vehicle, make of vehicle, and a license plate.

Curb The Danger Calls are the number of 9-1-1 calls made by the public to EPS to report an impaired driver.

EPS Intercepts from CTD are the number of occurrences where EPS made contact with the vehicle that was reported in from Curb The Danger.

Impaired Arrests from CTD the number of impaired driving arrests arising from Intercepts from CTD where the driver has a Blood Alcohol Concentration (BAC) of 0.08 or more, or there is other evidence to suggest a driver is impaired by alcohol, driving while impaired from narcotics or prescription drugs, or when testing for alcohol or drugs is refused.

Roadside Suspensions from CTD are the number of roadside suspensions that arised from EPS vehicle intercepts from Curb The Danger. The figures here do not count the roadside suspensions that occur as part of an impaired driving arrest. The type of Roadside suspensions in this measure arise from:

1. AZAT (Alberta Zero Alcohol Tolerance Program) – Issued to GDL drivers with a BAC above zero. 30 day suspension, 7 day vehicle seizure.
2. IRS (Immediate Roadside Sanction) – BAC of .05 to .08 - 72 Hr suspension, 3 day vehicle seizure, with longer durations for subsequent offences.
3. 24 Hr Suspension – No reasonable Suspicion or Grounds to proceed in a formal Impaired Investigation, but a 24 hr suspension is given on the grounds of public safety.

CTD Letters Sent to Registered Owners are the number of letters EPS sent to registered owners identified from a Curb The Danger call.
