I drive about 90 miles on the interstaates an back on a fairly regular basis.
In the stretch going and coming there are always two or three reecent scars where trucks have run off the road. Is a sleepy
run off the road a wreck?
No not sleepy, the black tread scars happen when a car cuts in front of a heavy truck and slams on the brakes or slows way down. A truck responds slowly.
I call it the reverse tailgate. Cut closely in front of another vehicle. There are TWO lanes. Use up the left lane that is why it is there. 2 vehicles in 2 lanes instead of packing the right lane.
Cars cause 3 times the accidents.
Cars drive in close packs instead of offsetting. And yes some ignorant truck drivers do tailgate also.
