Driving Over Fresh Line Paint: Illegal and Dangerous for Modern Tech

An orange, diamond-shaped construction sign on a BC highway reading Line Marking In Progress.Many drivers view wet highway paint as a nuisance. Driving over newly painted lines damages your vehicle, defaces road infrastructure, and creates severe safety risks for modern vehicles. Here is what British Columbia drivers need to know about the legal penalties and technical dangers of ignoring "Wet Paint" signs.

It is Illegal (BC MVA Section 143)

Crossing newly painted lines violates British Columbia traffic law. Under Section 143 of the Motor Vehicle Act, drivers must not cross a freshly painted line if a traffic control device (such as a sign or cones) indicates the line is wet.

  • The Penalty: Violators face a $109 fine.
  • Driver's License Impact: The ticket carries 2 penalty points.
  • ICBC Insurance Claims: Damaging public infrastructure by tracking through wet paint can result in a property damage claim submitted by the Ministry or its contractor directly to ICBC. Because you violated the MVA, you will likely be found at fault, impacting your insurance record and premiums.

Ruins the Retroreflectivity

Driving over a newly painted line ruins its ability to reflect light. Without the protective bead matrix embedded correctly, the paint wears away prematurely under standard traffic and winter plowing, forcing costly repainting cycles.

Blindfolding Your ADAS

Modern Advanced Driver Assistance Systems (ADAS) rely heavily on sharp edged road markings.

  • Camera confusion: Lane Keep Assist (LKA) and Lane Departure Warning (LDW) use cameras to track contrast edges.
  • Track tracking: Smeared, broken, or tracking paint lines distort the vehicle's visual baseline.
  • System shutdown: Distorted lines cause ADAS systems to misread lanes or abruptly disengage.
  • Erratic corrections: Confused systems may trigger false steering corrections, pulling your vehicle unexpectedly.

What Drivers Should Do

  • Watch the signs: Look for "Wet Paint" signs, cones, and flashing arrow boards.
  • Keep your distance: Drive with caution around paint striping trucks.
  • Never switch lanes: Do not cross a freshly painted line until you pass the end of the cones or the paint has completely dried.
