Big rigs banned from left lane on parts of I-70 in Colorado starting in August
A new law restricting commercial vehicles on I-70 in Colorado will go into effect in less than a month.
On August 7, 2024, the new Commercial Vehicle Highway Safety Measures law (formerly SB24-100), will go into effect in Colorado. The bill was signed into law by Colorado Governor Jared Polis on May 20, 2024.
The new law forbids commercial vehicles from traveling in the far left lane of I-70 in the following areas “unless specifically required or authorized to pass by law”:
- Between mile markers 115.5 and 131.0 (Glenwood Canyon)
- Between mile markers 169.5 and 173.0 (Dowd Junction)
- Between mile markers 180 and 190.5 (Vail Pass)
- Between mile markers 205.5 and 221.0 (Eisenhower-Johnson Tunnel)
- Between mile markers 224.0 and 228.5 (Georgetown Hill)
- Between mile markers 243.0 and 247.0 (Floyd Hill)
Another provision included in the law will expand the areas where truckers are required to carry chains between September 1 and May 31 to:
- I-70 west of mile marker 259 (Morrison)
- State Highway 9 from mile marker 63 to 97 (Frisco to Fairplay)
- U.S. Route 40 west of mile marker 256 (Empire)
- U.S. Route 50 west of mile marker 225 (Salida)
- U.S. Route 160 west of mile marker 304 (Walsenburg)
- U.S. Route 285 west of mile marker 250 (Morrison)
- U.S. Route 550 — Entire route
Additionally, the new law permits the Colorado Department of Transportation (CDOT) to establish heightened speed limit enforcement zones in Glenwood Canyon on I-70 eastbound from milepost 116.0 to milepost 131.0 and westbound from milepost 118.5 to milepost 131. CDOT will be required to post signage informing commercial drivers of the increased fines in the area.
