Reckless Driving Summons in Leesburg

My husband got pulled over tonight and the officer had told him he was speeding. My husband is foreign so he didn't really know how to deal with interaction and didn't ask any questions.

Therefore, the officer didn't even mention what speed he was going. Unfortunately our dashcam was also out of battery and didn't record this. Nonetheless, he has a clean record and no prior traffic offenses. We're reading online that this kind of charge can lead to jail time which is pretty scary. Is that likely for this offense? Should we look into a lawyer? Any advice around this before his court day is greatly appreciated.
