Read the full, current section at the official source: Cal. Civ. Code § 2100 (leginfo).
In Plain English
- Heightened duty: common carriers owe the utmost care and diligence — more than the ordinary reasonable-care standard.
- Who qualifies: buses, trains, taxis, shuttles, and rideshare services carrying passengers for reward.
- Must provide everything necessary for safe carriage and exercise a reasonable degree of skill.
- Easier to prove liability: the higher standard means smaller lapses can establish a breach.
Key Terms Defined
Common carrier
A business that transports passengers for reward — buses, taxis, trains, rideshare — subject to the utmost-care duty.
Utmost care and diligence
The heightened standard of care § 2100 imposes on carriers — higher than ordinary negligence.
Reasonable degree of skill
The competence a carrier must exercise to safely transport passengers.
Purpose & Context
Section 2100 recognizes that passengers entrust their safety entirely to a carrier, so it imposes the highest practical duty of care. This makes it easier for an injured passenger to hold a bus line or rideshare accountable.
Real-World Example
A bus driver brakes abruptly and a seated passenger is thrown and injured. Because § 2100 requires the carrier to use the utmost care and diligence, even a modest lapse in caution can establish a breach and support the passenger’s claim.

Why 2100 Matters
For injured people & families
As a passenger, you are owed the highest standard of care — which makes a bus line, taxi, or rideshare easier to hold accountable when you are hurt. See our California bus accident lawyer page.
For defendants
Common carriers face a heightened duty, so conduct that might not breach ordinary care can still create liability under § 2100.
