Is swerving (changing lanes quickly) a violation?

I can only find "reckless driving" which is defined by Makati Traffic Code as:

29. Reckless Driving – a person while driving a motor vehicle fails to take such
ordinary care as under the circumstances it is his legal duty to do to avoid
injury to person or property.
“Reckless Driving” o walang ingat na pagmamaneho - isang nagmamaneho
ng sasakyan na walang ingat. Katungkulan sa batas ang pagmamaneho
nang maingat.


Section 57. Reckless Driving. – Pagmamaneho nang Walang Ingat.

No person shall operate a motor vehicle on any road recklessly or without reasonable
caution considering the width, traffic, grades, crossing, curvatures, visibility and other
conditions of the road and the conditions of the atmosphere and weather to endanger
the property or the safety or rights of any person or to cause excessive or
unreasonable damage to the road.

Bawal magmaneho nang walang ingat at hindi isinaalang – alang.Ang lapad,
trapiko, ahon o lusong ng kalsada, krosing, kurbada, dilim o liwanag ng lugar at
iba pang kondisiyon ng kalsada at lagay ng panahon na maaaring magsilbing
panganib sa mga tao at ari-arian o maging dahilan nang pagkasira ng kalsada.

Meaning that any form of driving, including swerving, is not reckless driving, unless it endangers the body or object of a person (including yourself). Swerving in traffic, that is, changing lanes because of flow, cannot be reckless driving unless you change lanes without care for the safety of other persons and property.

Opinions? Anyone here actually ever charged with reckless driving?
