Typically, the rates for taxi cabs IS pretty high. I irsune several taxi accounts in Texas. With you starting a new venture you won't have any loss runs or transit logs to show for evidence, so it will be higher than if you had 3-5 years of experience. Remember that the rates in a smaller town or area will be lower that trying to irsune in a larger town,You need to check with your local jurisdiction to see WHAT is required as far as insurance goes. Some areas will allow you to irsune for State minimums (which you can get through your States Assigned Risk Pool or Fund) just finding an agent to write it would be the next step. If your local jurisdiction requires a higher limit of liability, or, if you are planning on entering any major airport, you may have to have higher limits of liability. This will increase the limits of liability required and cost you more money in the long run.What you need to do is call a local independent agent and ask them what they suggest. Just look for the PIA or Big I (Trusted Choice) logos, and you should be able to find an agent to help you. NJ also has the NJ Auto Agents Alliance maybe one of those agents could help you as well.Good luck with your endeavors and I hope this helps!
