Two important things about safe, defensive or advanced driving courses from Advanced Drivers of North America are that (a) we will work anywhere in the USA and Canada, as well the islands on either side of the continent, and (b) you will always get highly-trained instructors, not — to be frank — somebody who has received only a few days of severely inadequate training, themselves. (And yes, that really does happen.)
All of our behind-the-wheel training, except for any brief but necessary corrections to unsafe steering technique, is done on active roads — the only place where comprehensive training can take place, and where a very wide range of random risk scenarios can be encountered to facilitate an upgrade to relevant techniques for trainees’ future use.
Denver and Boulder are cities in which we have worked many times for several major clients and they are firmly among our favorite cities at which to run courses. This is for the simple reason that the area offers just about every conceivable type of road challenge, on which we can teach a very wide range of safety considerations and techniques. This type of variety is most important in developing drivers with a much broader and more effective defense against bad things happening.
