Question 1: May a sign language interpreter be used for the commercial driver’s license (CDL) general knowledge test?

Guidance: Test methods are governed by 49 CFR 383.133. Specifically, § 383.133(b)(3) states:

Each knowledge test must be valid and reliable so as to ensure that driver applicants possess the knowledge required under § 373.111. The knowledge tests may be administered in written form, verbally, or in automated format and can be administered in a foreign language, provided no interpreter is used in administering the test.
