* Most major US insurance companies will *not* directly accept a UK driving license as primary proof of driving history. They require a US driver's license. This is due to differences in licensing standards, record-keeping, and legal frameworks.
* What they *might* do: Some insurers *might* consider a UK license as *supplementary* evidence alongside other documentation. This could potentially speed up the process of obtaining a US license (which you'll need eventually) or help establish a driving history. However, this isn't guaranteed and is entirely at the insurer's discretion. They'll likely still request a US driving record if possible.
* The crucial step: You must obtain a Florida driver's license as soon as possible after arriving. Florida's Department of Highway Safety and Motor Vehicles (FLHSMV) will have specific requirements for converting your UK license or getting a new one. Once you have a Florida license, getting car insurance becomes significantly easier.
In short, you shouldn't focus on finding an insurer that accepts your UK license. Focus on obtaining a Florida driver's license first. Then, any major US auto insurance company will be able to provide you with a quote. You can then compare prices and coverage from companies like Geico, State Farm, Progressive, Allstate, etc. Using an online comparison tool can simplify this process.
