Your husband's speeding ticket could affect the employer's company car insurance if he is listed as a driver on it. As a rated driver on a policy for the commercial vehicle, his driving record (MVR) would be looked at as part of the rating process.
If instead the work vehicle is on the employer's personal auto insurance policy the out of state speeding ticket your husband received may not affect the rates if he is not listed as a driver.
If the vehicle he was driving was a company work truck it would be more likely that it would be covered under a company business/commercial policy in which the employees would need to be listed as drivers. In this scenario your husbands driving record could affect the rates since all drivers' MVRs would be looked at when the company's policy premiums are being determined.
Your husband may see if he can fight his ticket or get it reduced to a non-moving violation on his own if he does not wish to pay lawyer fees. Some clerk of the courts, the department you normally call for ticket payment information, will work with you on this over the phone.

[Let CarInsurance.com help you find affordable auto insurance now.] For example my husband just received an out of state speeding ticket and did not want it reported to his driving record so called the number on his ticket and the courts advised him on the phone that he could request a reduction in the ticket charge, to a non-moving violation. This request was accepted and he paid a slightly higher fine amount but kept the ticket off his record this way. Depending upon your husband's rate of speed and the state's laws in which he received the ticket he may be able to do something similar. |
