the answer is 30mph

The same as it is for any other vehicle.
Usually walking speed, -4-5 mph.
5 mph
When engaged, it means that the transmission will not shift any higher than second gear. While this limits the maximum speed of the vehicle (usually to around 40 mph), it provides a boost of extra power (for instance, if you happen to be towing a trailer, or hauling a heavy load, up a steep slope).Similarly, shifting to 1 means that the car will remain in first gear, giving you maximum towing power at the expense of speed (and gas mileage).
To find your towing capacity, weigh it as it would normally be loaded then weigh it with your trailer hooked up. Verify that you are not going over the front or rear maximum ratings on your truck while hooked up and as long as the weight does not exceed the maximum limit, you should be fine.
While towing a trailer on a highway with a 65 mph speed limit, you should adhere to that limit if it is safe to do so. Make sure your vehicle and trailer are properly equipped and balanced, and maintain a safe following distance from other vehicles. Drive at a speed that is comfortable and manageable given the conditions.
That's the maximum permitted speed on that section of road.
A posted speed limit sign indicates the maximum speed permitted on the roadway for daytime or nighttime. In the case of the example in the question, the permitted speed at all times would be 55 miles per hour.
