Penal Code section 499b concerns taking someone else’s bicycle or vessel without permission for temporary use or operation. It is a misdemeanor with different maximum penalties for the two property types. The prosecution’s label “joyriding” does not establish that the item was a bicycle or vessel, that permission was absent, or that temporary use was the purpose. Compare the actual count and facts with the current statute.
If you received a citation, keep the original and the date of any appearance. A complaint can allege another offense as well; this page addresses the section 499b task, not every possible property dispute.
Identify the property and the branch charged
Subdivision (a) concerns a bicycle taken without the owner’s permission “for the purpose of temporarily using or operating” it. Its maximum punishment is three months in county jail, a $400 fine, or both. Subdivision (b) uses the same temporary-use wording for a vessel, but permits up to one year in county jail, a $1,000 fine, or both. Neither subdivision itself is a felony.
The property description matters. A bicycle, an electric device, a boat or another craft should not be assigned to a branch from a casual name alone. Bring photos, registration or ownership documents if available and the exact description in the report. Counsel can decide whether a disputed item fits the charged term and whether another statute was also alleged. The two penalty ranges should not be swapped merely because both acts are sometimes called joyriding.
Examine permission and purpose when the taking occurred
The statutory phrase “without the permission of the owner” is a concrete issue, not a formality. Was there express permission for this use, a limited permission that may have been exceeded, or a genuine dispute about what the owner said? Preserve texts, rental or borrowing terms, timestamps and witnesses to the conversation. The fact that the people knew one another does not by itself settle permission either way.
The statute also specifies the purpose of temporary use or operation. A return, abandonment, transfer to someone else or later recovery may provide evidence about the purpose, but no one fact automatically proves it. Counsel should compare the person’s words and actions at the time of taking with what happened afterward. If the accusation instead concerns an intent to keep or sell the item, another charge may be at issue; that does not turn § 499b into a general theft statute.
If several people were present, distinguish who allegedly took the property, who used it later and what each person knew or agreed to. Mere presence beside a bicycle or aboard a vessel does not identify the person who took it. Keep any existing video, location history, ownership records and communications intact; do not alter them or contact witnesses to align accounts.
Avoid importing motor-vehicle joyriding rules
Vehicle Code § 10851 separately covers unauthorized driving or taking of a vehicle with temporary or permanent deprivation intent and has different charging and punishment provisions. A bicycle or vessel allegation under § 499b cannot be analyzed by copying a car-joyriding penalty or assuming every vehicle exception applies. The actual property and citation decide where the analysis starts.
For the vehicle comparison discussed here, see the firm’s joyriding guide. Keep section 499b’s bicycle and vessel provisions distinct from motor-vehicle rules.
Before a plea or hearing, have counsel review the charge, the owner’s account, any permission history and the evidence of temporary purpose. The Law Offices of David S. Chesley can discuss a California criminal property allegation on those facts. Contact the firm or call (800) 755-5174.
