High Road Vs The Book

I got a question about the stopping distance. High road says perception is 3/4 seconds. At 55 mph, you travel 60 feet in 3/4 second. The Wyoming book says 1 3/4 seconds. At 55 mph this accounts for 142 feet.

High road says, Braking distance is the distance it takes to stop once the brakes are applied. At 55 mph on dry pavement with good brakes, it can take a heavy vehicle about 170 feet and about 4 1/2 seconds to stop. The book says at 55 mph it takes about 216 feet.

High Road says Total stopping distance - At 55 mph it will take about 6 seconds to stop and your vehicle will travel the distance of a football field (60 + 60 + 170 = 290 feet). The book says at 55 mph, your vehicle will travel a minimum of 419 feet.

I guess what I'm wondering and what has just confused me, do other states have different readings. Do the tests very from state to state?

The cdl manual just varies from state to state. I studied by reading my state's manual and answering the high road questions as I went. You could just use the High Road program and still pass just fine though. There are not enough differences that it's worth worrying about.

Whaaaaat? Is the average Wyoming driver ASLEEP? Almost two seconds is RIDICULOUS!

Sorry, that doesn't help.

Hey Jason. Here's the situation........

The state CDL manuals are all based off of the Federal CDL manual. The Feds changed their numbers last year but most states are slow to update their manuals. The current version of our High Road Training still uses the old numbers but behind the scenes we're currently in the process of rewriting the High Road to reflect the changes. In fact, we're building a version that will be state-specific and account for all of the differences between the various state manuals and the Federal manual.

Sorry about the confusion but unfortunately many of the states have not caught up with the Feds yet after the updates were made. If they ask you on the exam, use the numbers from your state's manual.

Lol, WY isn't quite that slow just because the pronghorn out number the state residents. I looked at a couple of other states, and it said the same.

Oklahoma manual has the 419 feet and the test answer was more than a football field. Now you know the answer, not to worry.
