Not securing a child in a federally-approved car seat violates Nevada state law if the child: Is under 6 years old, and Is under 57 inches tall, and is not big enough for a booster seat. The penalties for violating NRS 484B.157 get harsher with each successive offense. A first offense carries $100 to $500 in fines, or 10 to 50 hours of community service. However, the judge will waive these requirements as long as the defendant completes a child restraint system training class within 60 days of the sentencing. A second offense carries $500 to $1,000 in fines, or 50 to 100 hours of community service. However, the judge will halve these requirements if both: the defendant completes a child restraint system training class within 60 days of the sentencing, and the defendant did not have the fine or community service sentence waived for his/her first offense. A third- or subsequent offense carries a driver’s license suspension of 30 to 180 days.
