Virginia family faces $576 toll charge for 45-mile RV trip on I-66 express lanes

A Virginia family was shocked to receive a $576 toll charge after driving their RV just 45 miles on I-66's express lanes. They expected to pay around $30 but were surprised by the high cost due to dynamic pricing for larger vehicles. The toll rates on I-66 vary based on traffic demand, and larger vehicles like the family's RV incur higher charges. The family learned that their RV did not qualify for certain other toll lanes, leading to the steep bill. To avoid similar situations, drivers are advised to plan trips during off-peak hours, check their vehicle's toll classification, and consider alternative routes. The family found that the express lane only saved them 20 minutes, which did not justify the expense.
