Free Colorado DMV Practice Permit Test - Practice Test 4 2026
This Practice Test 4 is modeled on the Division of Motor Vehicles (DMV) written knowledge exam, whose length the agency does not publish; to pass you need 80% correct. These 25 questions rotate through traffic laws, road signs, and right-of-way - the core topics the DMV tests most heavily. Every question includes an explanation, so you learn the rule behind each answer - not just whether you got it right.

1. What is Colorado's default speed limit on an open mountain highway when no other limit is posted?
- A. 45 mph
- B. 35 mph
- C. 40 mph (correct)
- D. 55 mph
Why: Unless a different limit is posted, open mountain highways in Colorado have a 40 mph limit. Narrow, winding mountain roads are lower, at 20 mph.

2. In Colorado, when is it illegal to pass a snow plow?
- A. Only when the plow is spreading sand or salt
- B. Only on interstate highways after sunset
- C. When plows work in a staggered diagonal formation (correct)
- D. Any time the plow is parked on the shoulder
Why: It is illegal to pass an authorized snow plow working in a staggered (tandem) formation with other plows. The blowing snow they create can also hide the plows from view.

3. In most states, which left turn may you make on a steady red light after a full stop, if no sign forbids it?
- A. From a two-way street onto another two-way street
- B. From any street when no oncoming car is in sight
- C. From a two-way street into a store's driveway
- D. From a one-way street onto another one-way street (correct)
Why: Most states allow a left turn on red from a one-way street onto another one-way street that carries traffic to the left. You must stop fully and yield to pedestrians and traffic first.
4. What color background is used for most warning signs?
- A. Red
- B. White
- C. Yellow (correct)
- D. Purple
Why: Most warning signs have a yellow background with black symbols or letters. Yellow signals caution - slow down and watch for the hazard described.
5. At an uncontrolled T-intersection, vehicles on the through road have right of way over:
- A. Vehicles already in the intersection
- B. Emergency vehicles using sirens
- C. Vehicles on the terminating road (correct)
- D. Pedestrians in a marked crosswalk
Why: At a T-intersection (where one road ends and meets another), vehicles on the through road (the top of the T) have the right of way over vehicles on the terminating road (the bottom of the T).
6. Your regular brakes have failed and pumping did not help. How should you use the parking (emergency) brake?
- A. Apply it slowly and gradually (correct)
- B. Pull it on as hard as you can
- C. Only after the car has stopped
- D. Apply it and release it rapidly
Why: Setting the parking brake too hard or too fast can lock the wheels and throw the car into a skid. Apply it slowly while you steer to a safe place.
