Speeding violations do not typically result in jail time though they often may result in a combination of additional points on your driving record, community service, and/or a requirement to attend driving school.

Repeated speeding violations can trigger jail time.
Speeding when it is excessive, becomes reckless driving -- for example going 25 miles over the limit in some states, or over going over 100 or 120 in other states.
In all states if you have been issued a speeding ticket but you do not turn up in court to challenge the ticket nor make the payment, you can be arrested and sent to jail.
A past criminal record can also result in enhanced penalties including jail term for speeding.
If you are caught speeding in certain places, it increases the chances of being jailed. For example, in some states, you can be sent to jail if you are caught speeding near a military base or a school or in a construction zone.
Although you are unlikely to be jailed for speeding, if you are caught speeding along with another offense like driving without a valid driver’s license or you are also charged with DUI, then you will likely be sent to jail.
