AMENDMENT 64 – New laws won’t change CSP’s enforcement of impaired driving

As new laws based upon Amendment 64 continue to regulate the possession and use of recreational marijuana, the Colorado State Patrol reminds motorists that driving while impaired by marijuana (or any other substance) is illegal.  Recent legal changes–which loosen regulations governing the purchase, possession and consumption of marijuana by people over 21–do not mitigate motorists’ responsibility to drive sober at all times.


Need to know!





  • Sell marijuana unless you are a licensed retailer
  • Attempt to purchase marijuana if you are under the age of 21
  • Possess more than one ounce of marijuana at a time
  • Smoke marijuana in public places
  • Consume marijuana in public clubs or venues (or anywhere that cigarette smoking is prohibited)
  • Attempt to transport marijuana in the occupant compartment of your car (including the glove compartment) in an open container
  • Attempt to transport marijuana beyond Colorado borders
  • Travel to Colorado and attempt to purchase more than a quarter-ounce of marijuana



All Colorado State Patrol Troopers are trained in the detection of impairment from alcohol, drugs and other substances; additionally, many Troopers have received additional training as certified Drug Recognition Experts (DREs).  During the course of a traffic contact, any driver suspected of driving while impaired by marijuana may be asked to complete voluntary roadside maneuvers and submit to a chemical test.  Refusal of a chemical test results in stricter penalties than compliance.


“The investigative process for marijuana impairment is the same as that of any other impairing substance,” Baker said. “Troopers have been making arrests for drug-impaired driving for many years.  The laws may be new, but our professional experience with impaired drivers is not.”


Troopers will remain on increased patrols through the New Year’s holiday, actively seeking and arresting impaired drivers.  The increased vigilance leading into 2014


the agency’s ongoing commitment to combatting impaired driving through intelligence-led enforcement strategies across the state.



“Our family has been protecting yours since 1935,” said Colonel Scott Hernandez, Chief of the Colorado State Patrol.  “We encourage motorists to support our efforts during the holiday season by reporting impaired drivers or other dangerous driving behaviors.”
