Entrances are divided into the following three classes according to their normal usage:
  1. Type "A" entrance. An entrance developed to carry sporadic or continuous heavy concentrations of traffic. Generally, a Type "A" entrance carries in excess of 150 vehicles per hour. An entrance of this type would normally consist of multiple approach lanes and may incorporate a median.

  2. Type "B" entrance. An entrance developed to serve moderate traffic volumes. Generally, a Type "B" entrance carries at least 20 vehicles per hour but less than 150 vehicles per hour. An entrance of this type would normally consist of one inbound and one outbound traffic lane.

  3. Type "C" entrance. An entrance developed to serve light traffic volumes. Generally, a Type "C" entrance carries less than 20 vehicles per hour. An entrance of this type would not normally accommodate simultaneous inbound and outbound vehicles. Possible examples include residential, farm or field entrances
