Look up any South Dakota plate on Jerk Alert to see the driving reports filed against it and its current Erk Score. Reports are submitted by drivers who saw the incident — a plate, a location, one of 25 fixed categories and a severity from 1 to 5. No owner lookup, and no way to find out who anyone is.
The current South Dakota plate, as Jerk Alert renders it.
Letters and numbers only. A plate with no reports comes back clean — that is the common result, and it is not an error.
Newest first. Hidden and deleted reports are excluded. Get the app to see reports near you as they are filed.
Call 911. A driver who is an active danger to other people is a police matter, and no app is a substitute for that call. Do not follow the vehicle, and do not try to get closer to read the plate.
Your local police department’s non-emergency line takes reports of dangerous driving that has already happened. What each agency will act on varies, and a report generally needs the plate, the location, the time, and what you saw.
South Dakota has a route a member of the public can use. You file a named form with the licensing agency.
This is a fitness-to-drive referral, not a bad-driving complaint. It is built around a medical, cognitive or physical condition, and it asks for the driver’s name and date of birth — which a witness holding only a plate number does not have. Reporting a stranger who tailgated you is not what this channel is for.
Filing on Jerk Alert takes about ten seconds and does not replace contacting the authorities. Pick the plate and state, choose the location from the list, tap one of 25 categories, and set a severity from 1 to 5. There is nothing to type, so a report is a fact pattern rather than an account.
If you are in immediate danger, call 911. Jerk Alert is a record, not an emergency service, and the Terms prohibit following, approaching, or identifying another driver.
An Erk Score is a plate’s running rating from 0.0 to 5.0, computed from the reports filed against it and weighted by whether the reporter is verified. Endorsements from other drivers are counted on the report itself and do not change the score. Deleted and hidden reports are excluded, so a score only reflects reports currently standing.
A plate with no reports has no score.
