Step-by-step explanation:
If the speed limit is not posted on roads or highways outside town, it is important to follow the default speed limit set by the law. In most cases, this default speed limit is based on a reasonable and prudent speed that is safe for the road conditions. For example, in many states in the US, the default speed limit outside towns is 55 miles per hour. However, it's always recommended to check your local traffic laws or consult the Department of Motor Vehicles for the specific speed limit in your area.
It's important to note that even if the speed limit is not posted, you still need to drive at a safe and reasonable speed. Factors like weather conditions, traffic density, and road condition should be taken into consideration when determining a safe speed to travel.
