Look out for the "gators" on the road, they're everywhere.
A "Gator" is a slang term for a piece of tire tread that has ripped loose from a damaged truck tire.
Smaller gators are not a tremendous hazard if you run over them but the larger ones can cause some problems.
Perhaps a bigger hazard is a vehicle that swerves to miss one, that's what I saw today which luckily did not cause the accident that it could have caused.
On a busy major highway just ahead of me today, one car drove over a gator at sixty miles an hour and it flipped up in front of the car behind him. That driver freaked out, swerved to miss it and almost lost control in front of lots of traffic including me.
Any kind of debris on the road can be dangerous, I once watched (seemingly in slow motion) as a large bolt was flung up by a passing pick up truck changing lanes in front of me. The bolt was spinning in the air at my eye level as I hit it at 50 mph. My windshield shattered in circular area about a foot around with a perfect clear Hex shape in the center where the head hit. It sounded like a gun shot as the safety glass did it's job and kept it from penetrating through the glass.
I felt the instinctive urge to swerve but kept the wheel firm and ducked instead. If I had swerved enough to miss it, I would have clipped the car beside me or worse.
Just another reason to leave plenty of space between vehicles on the highway, you can see any hazards further ahead of you and take safe evasive actions to avoid hitting the debris.
