No, unfortunately, it is not that simple. You should seek out referrals and recommendations from friends, family, and business associates. There are many factors to consider such as reputation, years in business, hours of operation, size and age of the fleet, licensing and insurance, customer service philosophy & back office support & management.
Please use due diligence in choosing your ground transportation service. If you are able to, take the time to visit their location and see their fleet first hand and while there do not be hesitant to ask any pertinent questions including for proof of insurance. If your are booking larger vehicles, especially buses, any reputable company should provide to you upon request their U.S. DOT number and the company name it is registered under. You can log onto the U.S. Dept. of Transportation – Federal Motor Carrier Safety Administration SAFER website and view whether they are in good standing.
