P19: Law Enforcement Suspects Drug Use

Definition:

Driver or non-motorist involved in the crash suspected by law enforcement to have used drugs.

Element Attributes:
  • No
  • Yes
  • Unknown

Unknown (from FARS Coding Manual): unable to take a position as to involvement (still may order an evidential test)

Rationale:

Drug-related crashes remain a serious traffic safety problem. Identifying crashes in which drugs may have been involved will help evaluate the effectiveness of programs to decrease the incidence of driving while under the influence of drugs.

This element is used in part to develop the crash derived element Drug Involvement (CD8).

Additional Information:

This element is reflective of the officer's opinion of the use drugs. The officer's opinion as to drug's contribution to the crash is recorded in the Driver and Non-Motorist Condition elements (P14, P24). It is based upon a factor or combination of factors such as:

  • His or her on-scene evaluation (Observation, Behavioral/Field Sobriety Test, e.g. eye gaze/nystagmus, walking a line)
  • BAC testing
  • Other sources (witness statements, coroner's report)
