The bill mandates that state employees involved in motor vehicle accidents or collisions resulting in serious injury or death must provide a urine specimen for alcohol and drug analysis under specific circumstances. This requirement applies if there is probable cause that the employee was operating the vehicle in violation of certain sections related to operating while intoxicated. The specimen must be provided to a peace officer within two hours of the incident, and the analysis will be conducted in accordance with existing laws. Additionally, the employee has the right to request an independent analysis of the specimen at their own expense, although the lack of such an analysis does not affect the admissibility of the results from the official analysis.

The bill also clarifies that this requirement does not apply if a blood, breath, or urine specimen has already been taken under the relevant chapter concerning operating while intoxicated. Furthermore, it defines "serious injury" as per the existing legal definition. This legislation aims to enhance accountability among state employees operating state-owned vehicles and ensure public safety following serious accidents.
