Welcome!

Some tips:
- Practice emergency brake on an empty road/space/car lot.
- Scan ahead.
- You will go where you look. So, concentrate on the road.

Go and download Twist of the Wrist. It teaches you all the technical know how of bike riding.

How to use them will require practice of course.

1. What bike are you using? Do you mean cornering at speeds above 20~30km/h or just turning at low speeds under 20km/h?

2. I've had my bike for nearly a month and still cannot filter properly, lol. I'm slowly getting better, but while I continue to adjust, I just find a space in the traffic jam where I can go in to let those faster riders pass. After it's clear, I begin to filter again. Those faster riders wait for no one, so there is no point letting them pressure you into an accident.

Assuming that this is filtering during traffic jam or near-standstill, do take care while doing this. In some cases, the car you end up behind will suddenly brake, or the car behind you doesn't notice that you've slipped into the gap. Occasionally there will be other cars from the other lanes that want to fill the gap as well.

The key is to find a big enough gap so that the riders tailgating you can pass. It's actually safer for you to be filtering at low speeds in a traffic jam because you're at less risk to be rear-ended by a driver who wasn't paying attention, or worse, sandwiched between cars.

On bigger highways like PLUS, you can opt to use the emergency lane instead of filtering, which is much safer bar the uncommon douchebag driver who will dive into the emergency lane. The use of that lane by motorcycles is sort of a grey zone though so do mind that.
