Out of the several Express lanes in Colorado, the I-25 lane is close to Denver, and allows drivers who have an ExpressToll account to speed up their journey times and reduce congestion.
You should never use Express Lanes as passing lanes, and you should only enter and exit through the dashed lines. Entering or leaving an Express Lane incorrectly over the double white lines may result in a fine up to $1,000.
In Denver, the minimum age for independent driving is 16. Individuals between the ages of 16 and 21 with a minor license have restrictions on the number of passengers they can carry, and a strict curfew. Learner’s permits can be issued from the age of 15, but a licensed adult must always be present in the vehicle if a learner is driving.
To obtain a full minor license, you must have held a learner’s permit for a minimum of 12 months. Minor licenses are valid until no more than 20 days after the driver turns 21, after which they must be renewed to obtain a standard license.
Please note, although you may hold a learner’s permit, the minimum age to rent a car with Hertz in Denver is 21.
