Vermont's general keep-right rule is found in 23 V.S.A. §1031.
On roadways of sufficient width, vehicles generally must be driven on the right half of the roadway unless a statutory exception applies.
Drivers may move left when overtaking and passing another vehicle traveling in the same direction, when an obstruction makes it necessary to move left, on certain three-lane roadways, or on roadways designated for one-way traffic.
Vermont's limited-access-highway regulations contain a more specific rule: drivers must keep to the right except when passing or when moving left is necessary to avoid merging traffic.
When one vehicle is overtaking another, Vermont law generally requires the passing vehicle to pass safely on the left. The driver being overtaken must give way to the right and may not increase speed until completely passed, except where passing on the right is legally permitted.
Vermont therefore combines a general right-side driving law with a stronger keep-right-except-to-pass rule on limited-access highways.
Exceptions
- Overtaking and passing another vehicle traveling in the same direction.
- Avoiding an obstruction when moving left is necessary and safe.
- Traveling on a roadway divided into three marked lanes where another lane position is permitted.
- Traveling on a roadway designated for one-way traffic.
- Moving left on a limited-access highway when necessary to avoid merging traffic.
- Following official traffic-control devices that lawfully direct use of another lane.
Penalties
Violations of Vermont's keep-right or passing rules may result in a traffic citation. The exact fine and total amount due depend on the specific provision charged and applicable court assessments.
Drivers should verify the current amount shown on the citation or with the Vermont court handling the case.
