Chevron Signs

Disrupt driver inattention, reduce speeds, and keep drivers on the roads at problematic rural curves.

Rural roads aren’t like urban roads. While they can feel safer due to their lower levels of traffic and complexity, the reality is nearly half of all fatal crashes occur in rural locations. Around 17,000 people are killed each year in rural road departure crashes.

The high rate of crashes in rural areas is caused by many factors, including high speeds, sharp turns, poor lighting conditions, and a lack of safety features like pavement markings and guard rails. Fortunately, many of these hazards can be mitigated with effective, if underutilized safety treatments.

One of the best ways of increasing driver awareness, reducing speeds, and keeping drivers on the road is with Carmanah’s MX Series Chevron Signs.


Featuring powerful LEDs and embedded connectivity, Carmanah’s chevron signs are proven to reduce in-curve speeds and roadway departures from rural roads, while
providing agencies convenient remote access to system locations, statuses, and settings.


  • W1-8 sign with LEDs embedded around the chevron symbol

  • Ultra-bright simultaneous flash pattern
  • Vehicle-activated or 24/7 operation
  • Single- or double-sided poles/mounts
  • Actionable email and text alerts
  • Built-in knockdown sensor
  • Quick setup and local access with MX Field App
  • Every system ships with 3 years of free connectivity, remote system access via MX Cloud

Understanding rural roadway departure crashes

Roadway departure crashes are incidents in which a vehicle “crosses the edge or centerline, or otherwise leaves the travelled way.” When a vehicle enters a curve, centrifugal force works to keep it moving in a straight path rather than following the curve of the road.

While rural road departure crashes can happen anywhere, they are more likely to occur on rural roads than urban ones because they typically have:

  • Poor driving conditions (e.g. potholes, snow and ice)
  • Missing safety features (e.g. pavement markings, guard rails, etc.)
  • Higher maximum speed limits
  • Less congestion, and less “friction” in general (e.g. traffic signals, pedestrians)
  • Inadequate nighttime lighting

Rural roads also tend to have have narrower lanes, with hazards like utility poles, trees, and other fixed objects located close to the roadway. And because rural roads are remote, the time to discover a crash are generally longer, with emergency services taking longer to arrive. (source, source)

  • Chevron signs have been shown to reduce nighttime crashes by up to 25%

  • Oversized chevron signs have been shown to decrease fatal and injury crashes by 15% 

  • Dynamic curve warning systems (with triggered lights) have been shown to result in speed reductions as high as 8.8 mph

Chevron sign placement

According to the MUTCD, chevron signs should be be positioned on the outside of a turn or a curve, “in line with and at approximately a right angle to approaching traffic.”

Spacing of chevron signs should allow the road user to have at least two in view at any given point, until the change in alignment eliminated the need for the signs.

For guidelines on chevron spacing, see the FHWA video to the left, or refer to Table 2C-5 in the MUTCD.

More rural road safety solutions

Chevron signs are a highly effective tool for slowing vehicles and reducing roadway departures at horizontal curves, but they aren’t the only solution Carmanah offers for rural roadways. Check out our Rural Roads Safety Solutions Digital Brochure for an overview of our entire rural product line, or select a product below.




SpeedCheck® advisory speed signs capture drivers’ attention and signal that speeds should be reduced with intelligent warning displays.

Intersection conflict warning systems reduce crashes at unsignalized crossings by warning drivers about oncoming cross traffic.

SpeedCheck® radar speed signs have an immediate and long-lasting impact on driver behavior and can reduce speeds by as much as 9 mph.

Flashing beacons and signs can be used to alert drivers to potentially hazardous conditions, including wildlife, loose rocks, and trail crossing warnings.
