Driving Test - Victorville? Speed limits (licensed, roach, lessons)

[tmdm]

Hello all,

I have a question relating to the US behind the wheel driving test and just looking for some advice!

I'm sitting my test in Victorville on Friday, i've recently moved here from the UK where i've been a licensed driver for 8 years. I needed to pass the test here as soon as possible so i'm able to get to work and take my wife to her daily classes...

I feel prepared for the test and have had a few refresher lessons, the worry I have is due to lack of availability i've had to book my test in Victorville, which is out in the desert.. or that direction at least. And having used google street view to view the roads, none of them seem to have any speed limits posted. Anywhere. Theres a few scattered speed limit signs here and there but probably one for every 3-4 miles. Just wondering how you'd all approach this when it comes to the test. The limits that are displayed seem to vary from 25, 30, 35, 40 and 45. It really seems to vary. I don't want to fail for something as silly as speeding when it can be avoided but not sure what to do if it's not posted on the roads.

Thanks so much all!
