What is the correct technique when preparing to exit a highway via a deceleration slip road (off-ramp)?

1. Signal in good time, maintain cruising speed until fully inside the deceleration lane, then brake progressively to the posted ramp limit
2. Brake heavily down to 30 km/h while still traveling in the main highway traffic lane
3. Turn off the highway across painted gore areas without signaling
4. Accelerate to maximum speed inside the exit curve to beat trailing cars
