Short answer. Reckless imprudence is carelessness so serious that the law punishes it as a crime, even though the person never meant to hurt anyone. Article 365 of the Revised Penal Code punishes the negligent act itself, and the harm it causes only fixes how heavy the penalty will be.
What the law says
Reckless imprudence consists in voluntarily, but without malice, doing or failing to do an act from which material damage results by reason of inexcusable lack of precaution on the part of the person performing or failing to perform such act, taking into consideration his employment or occupation, degree of intelligence, physical condition and other circumstances regarding persons, time and place.

What the Code actually punishes
The test is inexcusable lack of precaution, measured against the accused himself — his occupation, his intelligence, his physical condition, and the circumstances of person, time and place. A professional driver, a surgeon and a site engineer are each held to what their own calling demands. The act must be voluntary but without malice: you meant to do the thing, you did not mean the harm. Simple imprudence is the lesser form, where the danger was neither immediate nor clearly manifest. The Code also punishes more heavily an offender who fails to lend on the spot such help as he can give to the injured.
How the penalty is worked out
Article 365 does not carry one fixed penalty. It asks what the act would have been if it had been intentional — a grave felony, a less grave felony, or a light felony — and scales the punishment accordingly, with simple imprudence punished more lightly than reckless imprudence. Where only property was damaged, the sanction is a fine measured against the value of the damage. Those peso figures were rewritten by Republic Act No. 10951 (2017), which updated the money amounts throughout the Revised Penal Code. Older printings still show the 1930 values, so check which version a source is giving you before relying on any figure. Separately, Republic Act No. 9346 (2006) prohibits the death penalty anywhere in this Code.
What it does not cover
This article is not a catch-all for every accident. If nobody was harmed and no property was damaged, there is nothing to prosecute — material damage is part of the definition. It also does not apply where a special law already punishes the same careless conduct with its own penalty, and it gives way where the penalty fixed for the offence is equal to or lower than what this article provides. Courts are told to use sound discretion in fixing the penalty here, without the ordinary rules on mitigating and aggravating circumstances.
The civil side runs alongside
A negligence charge almost always carries a claim for damages — hospital bills, lost earnings, repair costs, and support for dependants where someone died. That civil liability is normally decided in the same criminal case unless it is reserved and filed separately. Employers can be drawn in for the negligence of their drivers and workers. Nobody can promise how a prosecution will end, and this page is general legal information rather than advice on your situation. If you have been charged after a collision or a workplace accident, or you were the one injured, you can book a consultation.
