Accidents caused by heavy trucks have dropped for years They’re a small percentage of the total number of accidents each year.
I cannot believe the behavior of many drivers.
The most common dangerous one is passing, then cutting back in less than a car length in front of the vehicle they've passed, and often slowing down.
Why did they bother to pass?
Usually there's no one passing behind them and an open empty highway in front.
I've seen a lot of dopes doing this right in front of large trucks, with the trucker having to jam on his brakes to avoid a rear end accident that would be "his fault".
Whenever possible, I prefer to have at least one tenth mile spacing, preferably two tenths.
That way if I, or someone else screws up we have plenty of room to recover without involving other vehicles.
