On a normal family trip in a passenger car with an available rear seat, how must an 18-month-old child weighing 25 pounds be restrained?
Correct answer: In a suitable rear-facing child seat in the rear seat.
This child is under two years old and under 40 pounds, so the rule requires a rear-facing restraint in an available rear seat. Use a seat that fits the child and follow its instructions.

A three-year-old weighing 30 pounds rides in a family car with a rear seat. Which arrangement meets Colorado’s age-and-weight rule when the seat fits and is used correctly?
Correct answer: A rear-facing or forward-facing child restraint in the rear seat.
For a child at least two but under four who weighs at least 20 pounds, a suitable rear-facing or forward-facing child restraint is required in an available rear seat. A child must also meet the restraint manufacturer’s limits.

On a normal private-car trip, a five-year-old weighs 45 pounds and meets the chosen seat’s manufacturer requirements. With a rear seat available, which choice meets the state rule?
Correct answer: A suitable child restraint or booster seat in the rear seat.
Children at least four but under nine who weigh at least 40 pounds must use a child restraint or booster in an available rear seat. The seat’s own age, height, weight and usage requirements still apply.

A child has just turned eight and weighs 60 pounds. On an ordinary family-car trip, does the eighth birthday by itself allow the child to stop using a child restraint or booster?
Correct answer: No, the child-restraint requirement generally continues until age nine.
Colorado’s current rule covers children under nine, not just those under eight. Use a fitting child restraint or booster as applicable, according to its instructions; the age change took effect in 2025.

A nine-year-old can sit correctly for the whole trip and the vehicle’s lap-and-shoulder belt fits properly. In an ordinary passenger car, what does the age-nine rule permit?
Correct answer: Using the properly fitting vehicle belt instead of a booster.
A child from age nine until eighteen must still use a suitable child restraint or a properly worn safety belt. Reaching nine is not permission to ride unrestrained or use a belt that does not fit.

A 17-year-old passenger says a rear-seat belt is optional because the adult seat-belt rule mentions front seats. On an ordinary private-car trip with no exemption, is that correct?
Correct answer: No, the under-eighteen passenger rule still requires proper restraint.
The child-passenger requirement applies from age nine to under eighteen and is not limited to front seats. A 17-year-old passenger needs a properly fitting belt or suitable child restraint.

Which belt position matches Colorado’s definition of proper safety-belt use for a child using the vehicle belt?
Correct answer: Shoulder belt across shoulder and chest; lap belt low across the hips, touching the thighs.
The shoulder portion belongs across the shoulder and chest, while the lap portion lies across the hips touching the thighs. A child who cannot get a proper fit needs an appropriate restraint rather than a misrouted belt.

A rear-facing child seat would fit physically in the front passenger position, but that position has an active airbag. Is that a safe place to install it?
Correct answer: No, do not put a rear-facing child restraint in front of an active airbag.
CDOT warns against placing a rear-facing restraint in front of an active airbag. Physical space alone does not establish a safe installation; follow both the vehicle and child-seat instructions.

A parent rides as a passenger while a friend drives the parent’s child on a normal private-car trip. Who has the child-restraint responsibility assigned by this provision?
Correct answer: The parent who is present in the vehicle.
When a parent is in the vehicle, this provision assigns the parent responsibility for providing the child’s restraint and ensuring its proper use. This does not excuse anyone from other applicable safety duties.

You drive a neighbor’s child on a private trip and neither parent is in the car. Who is responsible under the child-restraint provision for ensuring the child has and properly uses the required restraint?
Correct answer: You, as the driver transporting the child.

A booster’s label requires at least 50 pounds. Your five-year-old weighs 45 pounds. Does meeting Colorado’s general age-four and 40-pound category make this particular booster suitable?
Correct answer: No, the manufacturer’s requirements for that booster must also be met.
The law requires correct use according to the manufacturer’s instructions as well as meeting the legal age-and-weight category. Choose a restraint appropriate for this child rather than ignoring a 50-pound minimum.

An adult in the front passenger seat of an ordinary belt-equipped car has no exemption. Does a short trip on a public street remove the requirement to buckle up?
Correct answer: No, the front-seat passenger must wear the belt during the trip.
The ordinary requirement covers the driver and front-seat passengers while the car is operated on a street or highway. A short distance or low speed is not one of the listed exemptions.

Your front seat has a lap-and-shoulder belt system. Is fastening the lap part while placing the shoulder part behind your back proper use?
Correct answer: No, wear both parts of the installed restraint correctly.
An installed lap-and-shoulder system is intended to be worn together. Putting the shoulder belt behind your back is not proper use of that system; an airbag does not replace it.

Someone seeks the state’s safety-belt exemption for a disabling medical condition that prevents appropriate restraint. What documentation does that exemption require?
Correct answer: A physician’s written statement certifying the condition and why the restraint is inappropriate.
This exemption requires a physician’s written certification of the physical or psychological disabling condition and an explanation of why the restraint is inappropriate. Discomfort or an unsupported assertion is not the specified documentation.

A 17-year-old driver has a rear seat with two safety belts and three passengers who are otherwise permitted to ride. May all three sit in that rear seat?
Correct answer: No, the rear passenger count must not exceed the number of belts.
For a driver under eighteen, the number of back-seat passengers may not exceed the available seat belts. Other licensing restrictions may also apply; meeting one rule does not cancel them.

A 17-year-old drives a car with a wide front bench and enough belts. Assuming the passengers are otherwise permitted, may two passengers sit in front beside the driver?
Correct answer: No, this rule allows no more than one front-seat passenger.
The under-eighteen driver rule limits the front seat to one passenger, regardless of extra width or belts. Rear-seat capacity and other minor-license restrictions are separate requirements.
