Interstate System Weight Limits

[David Brady]

Tom,

From the Federal Highway Administration web site:
http://vsw.fhwa.dot.gov/qa/qa.jsp?catego...R%20658.17
Correct me if I'm wrong, but I think the drive/tag axles on an
LXi qualify as a Tandem axle.

*May States set weight limits on the Interstate
System at less than the Federal maximum weight limits?*

"No. When Interstate System weight limits were raised to the current
levels in
1974 (20,000 pounds single axle, 34,000 pounds tandem axle, 80,000 pounds
overall gross weight limits, plus bridge formula limits), States were
not required
to raise their limits accordingly, although most did. However, six
contiguous
States in the Mississippi valley, referred to as the "barrier States,"
did not
and effectively limited the weight for all vehicles moving across them to
their own limits. This was changed in 1982 when Congress established
Interstate System weight limits as minimums as well as maximums."

*What is the definition of a tandem axle?*

"It is two or more consecutive axles over 40 inches but not over 96 inches
apart. If there were 3 axles within that distance, they would be considered
a tandem axle for the purpose of Interstate weight limits."

Best regards,
