The bus apparently came down Garrison Avenue and kept going through what's ordinarily a busy intersection on Cedar Lane, then barreled across a sidewalk seating area and shattered the front of Carly'z Craze, a clothing and fashion accessories store shortly after 3 p.m.
Members of the Teaneck Volunteer Ambulance Corps took the driver from D&M Tours in Paterson to nearby Holy Name Medical Center.
His condition couldn't be immediately determined.
Fortunately, the only other "casualty" was a clothing dummy that got knocked head-first onto the sidewalk.
City officials were checking on the extent of damage to the building.
