Five minutes. That is how long a stationary vehicle's engine may run in any 60-minute period under Vermont's idling law, and it catches plenty of truck drivers who are used to warming up a cab in the cold. If you are studying for a Vermont CDL, the idling rule is one of several state-specific truck rules worth knowing before test day, along with the penalties that follow commercial drivers on their record.
What is Vermont's truck idling rule?
Vermont limits a stationary vehicle to five minutes of engine running in any 60-minute period. Fines for idling are capped at $10 for a first violation, $50 for a second and $100 for a third or later violation. Those amounts are small next to other trucking penalties, but a ticket can still cost you time and your employer's patience. Winter makes the rule feel unfair, because cold cabs and cold engines are real, so plan stops with the limit in mind and check the current rule for any listed exceptions.
Winter driving as a Vermont CDL holder
Vermont's roads climb and twist, and the I-89 and I-91 corridors run north and south through the state. Winter weather makes every CDL rule harder to follow, from following distance to stopping before a railroad crossing. The CDL manual's general advice applies here: slow down early, leave more room than you think you need and avoid sudden braking or steering on slick pavement. Your state manual and employer will have the specific policies for chains, closures and equipment, so check those before the first storm.
Cold weather is not an excuse for a rushed pre-trip inspection. Walk the whole truck every time, even when it is snowing, and clear snow and ice from the cab, mirrors, lights and cargo area before you roll.
Railroad crossings and serious violations in Vermont
Vermont ties disqualification to your record, and the periods grow quickly. A second railroad-highway crossing violation within three years brings a 120-day disqualification, and a third brings one year. Serious traffic violations stack the same way: two within three years bring 60 days, and a third brings 120 days. Because winter makes stopping distances longer, a crossing that feels easy in July can turn into a violation in January.
- Second railroad crossing violation in three years: 120 days disqualified.
- Third railroad crossing violation in three years: one year disqualified.
- Two serious traffic violations in three years: 60 days disqualified.
- A third serious violation in three years: 120 days disqualified.
What does a Vermont CDL require?
The Vermont Department of Motor Vehicles issues CDLs that are REAL ID compliant. The state does not issue a non-REAL ID version of a CDL, so bring the documents needed for REAL ID when you apply. The standard path is a commercial learner's permit (CLP), a period of practice and then the skills test. Vermont's CLP is valid for one year, and you must wait 14 days after getting it before you take the skills test.
Who can ride with a Vermont CLP holder?
A Vermont CLP holder must be accompanied by a CDL holder sitting in the front seat. There is one exception for larger vehicles. If the vehicle is designed to carry more than 15 passengers, the supervising CDL holder sits directly behind the driver or in the first row behind. Plan your practice with someone who understands that seating rule, because a ride that breaks it is not valid supervised driving.
Vermont school bus endorsement: why it works differently
A Vermont Type II school bus endorsement requires attending a Vermont school bus clinic, and it cannot be added to an out-of-state CDL. If you are moving to Vermont for a school bus job, do not assume your existing endorsement will carry over. Contact the Vermont DMV early to learn how the clinic fits your timeline.
