Uh, I hope you know that the law on that has changed. Failure to present is no longer an offense, and it is not listed as grounds for either revocation or suspension of the license. The law was changed in 2009, and it took away the ability to seize the CHL for failure to present.
Be aware that is a personal posting and not the wording of the current law.
