“Recently, I had need of technical information regarding those low profile concrete objects found in commercial handicapped parking areas, referred to as “wheel stops” / “car stops” / “tire stops.” At first glance, a person may wonder: “what technical information can possibly be associated with a plain stationary concrete object with no moving parts?” Well, as it turns out, Dr. Presswood furnished me with title, section, and paragraph of the ADA, ANSI and ASTM regulations and standards where “wheel stops” are referenced and the characteristics of what constitutes a “wheel stop.” Dr. Presswood dispelled any concerns I had about “wheel stops” when he unequivocally opined that “wheel stops” should never be used, period. By education, work history, and experience, I consider Dr. Presswood’s opinions on technical issues within his areas of expertise unimpeachable. Thank you, Dr. Presswood, for the pleasant experience I had working with you.”
