I've always understood that, as the former version of he NYS manual used to say, ball-banking should be done in a standard passenger car, not a truck or sports car. This is because a stiff suspension or a high Cg will skew the results.
I can't find any reference to this in the National MUTCD or the current Green Book. Am I missing something?
I once heard of a paper showing that vehicle type doesn't have much impact on the ball bank indication. Can anyone tell me where to find information confirming or refuting this assertion?
I'm asking because Management wants to replace our lone passenger car with an SUV. It makes sense, because it has to double as a construction inspector's vehicle.
