Single Solid White Line Means

Why are the solid white lines unlike on metropolis streets than on the interstate?

Ed from Frederick writes, "What'due south driving you crazy? On the interstates you lot are non supposed to cross a solid white line. In the city all the plow only lanes are wholly marked with solid white lines. Why are city turn lanes not marked with short dashed lines like the go out only lanes on the interstate? Is it any wonder yous see then many people breaking the law on the interstates?"

There is a misconception, by many drivers, that you are not allowed to cantankerous a solid white line on or off the interstates. It is legal, although "discouraged," to cross a single solid white line. It is illegal to cross double white lines on or off the interstates.

All states, including Colorado, follow the guidance for roadway markings from the Federal Highway Assistants'due south Manual on Uniform Traffic Control Devices (MUTCD). In Chapter 3B, Pavement and Adjourn Markings, in section 3B.04, Standard 20 information technology states, "Where crossing the lane line markings is discouraged, the lane line markings shall consist of a normal or wide solid white line." In that same section at Standard xxx it states, "Where crossing the lane line markings is prohibited, the lane line markings shall consist of a solid double white line."

I remember around 10 years ago talking to a person in Douglas County Public Works virtually the double white line feature they installed in parts of Highlands Ranch. Information technology was done, they said, to protect bike riders in the bike lane from right turning drivers. The double white lines were painted only before an intersection where correct turns on cherry-red were frequent. The lines prevented drivers stuck in a queue at a red low-cal from moving over into the bike lane to make the right plow on cherry. The lines were removed several years later.

Every bit for unmarried solid white lines indicating turn lanes on metropolis streets, the MUTCD guidance in section 3B.04.25 states, "On approaches to intersections, a solid white lane line marking should exist used to carve up a through lane from an added mandatory turn lane." The key word in there is 'should'.

There is besides guidance in subsection 6 that states, "A dotted white line marking shall be used equally the lane line to separate a through lane that continues across the interchange or intersection from an adjacent lane for any of the following conditions: A deceleration or acceleration lane, a through lane that becomes a mandatory exit or plough lane, an auxiliary lane 2 miles or less in length between an entrance ramp and an exit ramp, or an auxiliary lane 1 mile or less in length between two next intersections."

Those rules tin exist modified where lane changes might cause conflicts. In those cases, a wide or normal solid white lane line may extend upstream from an intersection. And in the case of a lane drop at an exit ramp or intersection, such a solid white line may replace a portion, merely not all of the length of the broad dotted white lane line.

The merely specific instance I could find in the Colorado Revised Statutes regarding this result is from CRS: 42-four-603: Obedience to official traffic command devices. "(i) No driver of a vehicle shall disobey the instructions of any official traffic control device including any official hand betoken device placed or displayed in accordance with the provisions of this article unless otherwise directed by a police officeholder subject area to the exceptions in this article granted the driver of an authorized emergency vehicle."

Bottom line, pavement markings on city streets or on the interstates volition atomic number 82 you the right way if you are making a plough. And unless otherwise posted by a sign, in Colorado crossing a single white line is discouraged, but isn't illegal.
