How to Report Road Hazards on CB Radio

When you spot a road hazard, reporting it on CB channel 19 is a trucker courtesy that can prevent accidents. Here is the proper format:

Include direction and highway — “Northbound I-81...” or “Westbound I-40...”

Specify the lane — “...in the hammer lane...” or “...in the granny lane...”

Give mile marker — “...at mile marker 215.”

Describe the hazard — “Big gator,” “bear in the median,” “brake check at exit 42.”

Full Example Report

“Breaker one-nine, you got a big gator in the hammer lane, northbound I-81 at mile marker 215. Watch your tires, drivers.” This gives everything other drivers need: direction, highway, lane, location, and hazard type. For large hazards that block a lane, also call 911 or your state's highway patrol number. See our reporting guide.

Road Hazard Slang FAQ

Common questions about trucker slang for road hazards and CB radio terms

What is an alligator in trucking slang?

An 'alligator' (or 'road gator') is trucker CB slang for a piece of tire tread or blown tire casing lying on the road. The term comes from the visual resemblance between chunks of dark, bumpy rubber and an alligator's scaly back. Road gators primarily come from retreaded tires on commercial trucks and can weigh 20-30 lbs, posing real danger to vehicles that hit them at highway speed.

What does 'bear' mean in trucker slang?

A 'bear' is CB radio slang for a law enforcement officer, typically a state trooper or highway patrol officer. Variations include 'Smokey bear' (named after the Smokey Bear hat many state troopers wear), 'bear in the air' (police helicopter or aircraft), 'bear in the bushes' (hidden speed trap), and 'full-grown bear' (state trooper as opposed to local police). The term became famous through the movie Smokey and the Bandit (1977).

What is the 'hammer lane' in trucking?

The 'hammer lane' is trucker slang for the left lane (fast lane/passing lane) on a highway. The term comes from 'hammer down,' which means to drive fast or accelerate. The left lane is where drivers go faster, hence the 'hammer lane.' The right lane is called the 'granny lane' because slower traffic typically stays right. Proper CB usage: 'You got a gator in the hammer lane at mile marker 42.'

What does 'bear bait' mean in CB radio?

In CB radio slang, 'bear bait' refers to a vehicle (usually a car) driving well above the speed limit ahead of you. The idea is that the speeding vehicle will attract the attention of police ('bears') and get pulled over before you do — essentially 'baiting' the bears so you can pass safely. Some truckers informally use faster vehicles as inadvertent scouts for speed traps, though this is obviously not a reliable safety strategy.
