It is an offense to drive without insurance, and the penalty for non-insurance is a range of 250 to 500 Dollars or around 10 days in jail for the first offense. For the second time offense, you will be required to pay a minimum fine of 350 Dollars or 10-day imprisonment. Your driving license will also be revoked for 3 months. Five points will also be deducted from your driving record. If this offense is repeated for the third time, a fine of 500 Dollars is imposed or imprisonment for not less than 6 months or both.
