SUMMARY: NHTSA is proposing a rule prescribing procedures for the assessment of civil penalties and for interpreting the factors for determining the amount of a civil penalty or the amount of a compromise under the National Traffic and Motor Vehicle Safety Act (Safety Act)@ to implement the Moving Ahead for Progress in the 21st Century Act (MAP?C21). MAP?C21 states that the Secretary of Transportation shall determine the amount of civil penalty or compromise under the Safety Act. MAP?C21 identifies mandatory factors that the Secretary must consider and discretionary factors for the Secretary to consider as appropriate in making such determinations. MAP?C21 further directs NHTSA to issue a rule providing an interpretation of these penalty factors. NHTSA is also proposing to update our regulations to conform it to the statutory civil penalty maximums enacted in MAP?C21@ the increased penalties and damages for odometer fraud@ and the statutory penalty for knowingly and willfully submitting materially false or misleading information to the Secretary after certifying the same information as accurate.
