The solution to strengthening your impaired driving crashes is to
SHOW how the crash could have been avoided or severity decreased by a
non-impaired driver. To do this you can apply the nearly lost art of time and distance evaluation and calculations.
Most law enforcement officers are discouraged to attempt much in-depth time and distance and end the wreck investigation when impact speeds are calculated. WHY? WHY IGNORE something that can be so beneficial to your case?
The answer is simple, most investigators simply were not properly trained in time and distance during their initial phases of reconstruction. Instructors trying to cover a LOT of material in a SHORT period of time is a recipe for DISASTER when it comes to you fully understanding time and distance.
