Driveway reflectors
Blue is the preferred color, but colorless (white) reflectors are acceptable.

Do not use red or yellow reflectors because drivers may confuse them with motor vehicle lights.

Some stores carry reflectors already attached to a long wire rod that can be pushed into the ground. These are acceptable.
Clearing your driveway of snow
When marking driveway openings along a roadway with reflectors, follow these guidelines:
- Select reflectors that are at least three inches wide
- Use double-sided reflectors and position them so they can be seen from both directions
- Place reflectors at least 12 feet away from the outside edge of the shoulder
- Put reflectors no higher than five feet above the ground.
- Do not place reflectors on mailboxes or permanent posts
