Warrantless DUI Arrest

Can police make a warrantless DUI arrest if they did not observe the suspect driving?

Yes. Police can make a warrantless DUI arrest even if they did not observe the suspect driving.

Observation of Crime Usually Required

Generally, police must observe a crime before they can make a warrantless arrest. (see Penal Code § 836) However, a peace officer with probable cause could arrest a person for misdemeanor driving under the influence of alcohol or drugs not committed in the officer’s presence where evidence could be destroyed unless the person was immediately arrested.

Observation of Driving Not Required for Warrantless DUI Arrest

Vehicle Code § 40300.5(e) created an exception to the presence requirement of Pen C § 836, because evidence could be destroyed by the simple passage of time unless the person was immediately arrested. However, this does not authorize a peace officer to forcibly enter a residence to effect such an arrest. People v. Schofield (Cal. App. 2d Dist. 2001), 90 Cal. App. 4th 968.

Police can also make a warrantless arrest if:

  • The driver is involved in a traffic crash.
  • The driver is observed in or about a vehicle that is obstructing a roadway.
  • The driver will not be apprehended unless immediately arrested.
  • The driver may cause injury to themselves or damage property unless immediately arrested.

Specific Examples

In Shaffer v. Department of Motor Vehicles, the warrantless DUI arrest of the driver was valid even though the arresting officer did not see plaintiff drive. In that case, a citizen complained and the officer observed visible paint transfer on the driver’s car and that the driver was intoxicated to the point of incompetence. The 1st District Appellate Court ruled that under Vehicle Code § 40300.5, when there has been a traffic accident, an officer having probable cause to believe that an involved driver “had been driving while under the influence of intoxicating liquor…” may make an arrest without a warrant. 

Similarly, in People v. Burton, 219 Cal. App. 4th Supp. 9, the warrantless arrest for misdemeanor driving under the influence was proper where a civilian witness observed defendant driving erratically and an officer then located defendant standing near his truck, noticed signs of intoxication, and confirmed that he had been driving the truck.

Can Local Police Stop Cars on the Freeway?

Yes. Local police can stop cars on the freeway or highway. In fact, any member of California law enforcement can generally enforce the laws anywhere in the state. This includes sheriffs, park rangers, harbor patrol, railroad police, and many other branches of law enforcement.

Why Can Police Stop Cars on the Freeway?

In California, almost all state and local law enforcement agencies have authority throughout the entire state. This means they can stop a vehicle on the freeway and can arrest persons for whom they have probable cause. For an exhaustive list, see Penal Code § 830-832.18.

Some of the better known state agencies are:1

  • California Highway Patrol
  • University of California Police
  • Cal State University Police
  • Department of Corrections and Rehabilitation
  • Department of Fish and Game
  • Department of Parks and Recreation
  • Department of Forestry and Fire Protection
  • Department of Alcoholic Beverage Control
  • California Exposition and State Fair Marshalls
  • Department of Cannabis Control

There are, however, many many more state agencies that have police authority throughout the state:

  • Department of Consumer Affairs2
  • Department of Motor Vehicles3
  • California Horse Racing Board4
  • Department of Housing and Community Development5
  • Department of Financial Protection and Innovation6
  • Department of Justice7

There are also many local agencies that have police powers anywhere in the state of California:

  • All county sheriffs and city police officers8
  • Community College Police9
  • Housing Authority Patrol Officers10
  • Municipal Security Officers11

Local agencies have some limits on their policing. Fore example, local police can only police:

  • Public offenses in their jurisdiction;
  • With permission from other law enforcement;
  • To prevent danger to person or property or escape of the perpetrator.

Three agencies from other states have limited police power to stop cars a freeway. They are the Oregon State Police, the Nevada Department of Motor Vehicles and Public Safety, and the Arizona Department of Public Safety. These agencies have police powers up to 50 miles inside California if:

  • The California Highway Patrol requests their help, or
  • Law enforcement services are necessary to preserve life 12
