Truck Rollover Warning: Ramp

Trucks risk rolling over on this ramp; reduce to 25 mph.

Warns drivers of large or top-heavy vehicles that the ramp curve ahead can cause a rollover if entered too fast. Even at the posted advisory, trucks should test braking before the curve and stay alert; the geometry is sharp enough that a moment of inattention is enough to tip the load.
