What happens if the police forgets to ask you to sign the citation?

If the police forget to ask you to sign a citation, it typically does not invalidate the citation itself. The signature is often an acknowledgment of receipt rather than an admission of guilt. However, if the citation is contested in court, the absence of a signature may be brought up as a point of contention. Ultimately, it's best to comply with the citation process and consult legal counsel if there are concerns about its validity.
