# What is DataQs?

FMCSA's system for challenging inaccurate inspection, violation or crash data.

Carriers and drivers file a DataQs request when they believe an inspection or crash record is wrong or incomplete. The state agency that reported it reviews the request.

If the challenge is accepted, the record is corrected or removed, which can lower CSA scores.
