Short answer. No. The Civil Code prohibits a common carrier from eliminating or limiting its safety obligation to passengers by any means — including ticket conditions, posted notices, or any other statement. The common carrier's responsibility cannot be eliminated or limited by stipulation, by the posting of notices, by statements on the tickets or otherwise.
What the law says
The common carrier's responsibility prescribed in the preceding article cannot be eliminated or limited by stipulation, by the posting of notices, by statements on the tickets or otherwise.

Why the disclaimer on your ticket does not work
Article 1760 lists every method a carrier might try to use to escape its passenger safety obligation — and then prohibits all of them. Written stipulations in the ticket contract, posted notices on the vehicle or at the terminal, printed statements on the ticket itself, and any other means are all ineffective. The statutory duty to carry passengers safely using the utmost diligence of very cautious persons is not a contractual obligation that can be bargained away. It is a legal requirement that exists independently of whatever the ticket says.
The policy behind the prohibition
The public rides common carriers because they have no practical alternative for much of their travel. A passenger boarding a bus in the terminal has no meaningful ability to negotiate the terms printed on the ticket — and often does not even read them. The law recognizes this power imbalance and removes the safety obligation from the realm of contract entirely. A carrier that is allowed to disclaim liability through fine print would have every incentive to do so while cutting corners on safety. The prohibition prevents that outcome by making the duty non-waivable, regardless of what the carrier writes on the ticket.
What claims you may still have
If you were injured aboard a bus, jeep, ship, or other common carrier, the disclaimer on your ticket or at the terminal cannot be used to defeat your claim. You have the right to seek damages for injuries caused during your transport. The carrier must show that it exercised the utmost diligence — if it cannot, it is liable. In appropriate cases, you may also be entitled to moral damages and, if the carrier acted in bad faith or with gross negligence, exemplary damages on top of actual compensation. The existence of a disclaimer does not diminish any of these remedies.
A note on what carriers can legitimately do
The prohibition is specifically on eliminating or limiting the carrier's safety obligation to passengers — what the "preceding article" (Art. 1755) establishes. This does not mean a carrier can never limit any aspect of its contractual relationship with passengers. There may be other terms — baggage policies, delays, schedule changes — that are not covered by the Article 1755 passenger safety obligation and may be regulated by agreement. But for personal injury during transport, the disclaimer is legally void. Do not let the carrier use the ticket's fine print to discourage you from asserting your rights.
