DWI Definition and Implications
Driving While Intoxicated (DWI) in New Hampshire encompasses both alcohol and drug impairment, representing a serious legal offense with significant consequences.
Under New Hampshire law, you’re at risk of being charged with DWI if your Blood Alcohol Concentration (BAC) is 0.08% or higher, but impairment signs alone can lead to charges even below this limit.
DWI is treated as a criminal offense without lesser charges like “Driving While Ability Impaired.”
Convictions can result in severe penalties, including fines, license suspension, and a permanent criminal record, impacting your future opportunities and personal life significantly.
BWI and Its Relevance
BWI, or Boating While Intoxicated, is a crucial aspect of New Hampshire’s approach to maintaining safety on the water. It prohibits impaired operation of any watercraft, much like DWI laws.
To understand its relevance, consider these key points:
- The legal blood alcohol limit for boating is .08%.
- BWI offenses carry similar penalties to DWI, including fines and potential jail time.
- Enforcement of BWI laws helps prevent accidents and fatalities.
- A zero-tolerance policy underscores the significance of safety on the water.
Understanding BWI is essential for responsible boating and ensuring everyone’s safety.

A DWI conviction involves penalties such as fines from $500 to $1,200, a license suspension lasting 9 to 24 months, and mandatory enrollment in an impaired driver education program.
If you face Aggravated DWI charges, the consequences intensify, including fines between $750 and $2,000, jail time, and longer license revocation.

When submitting job applications, particularly for positions involving driving, your driving record may hinder your chances, as employers frequently conduct background checks.
Additionally, you might face mandatory SR-22 insurance requirements, which can be costly.
Rental car companies may also deny service, limiting your travel options and increasing expenses due to these collateral consequences.
