Parking, Reversing & Roadside StopsStandalone practice
Before leaving an ordinary vehicle unlocked and unattended, with no remote-start or qualifying security system in use, what must the driver do?
Correct answer: Stop the engine, lock the ignition, remove the key and set the brake.
Why
Stop the engine, secure the ignition, remove the key and set the brake. Use Park or an appropriate gear, and on a grade turn the wheels so the vehicle cannot roll into traffic. Colorado permits a remote starter or adequate security measures that prevent unauthorized operation under a separate exception. Local idling rules can still apply.
